I have activity start time and and total hour i just want to find the end time of that activity i mean time when activity finished ?
for example I start my activity
for
$hour = 24:60:08 // 24 hour 60 min 8 min total hour
$starttime = 13:09 // using 24 hour format it 01:09
//means activity start at = 13:09
$endtime = ?
I want to find out the the time finished time of an activity
Thanks
You can with adding to time exploded hour like following:
$hour = '24:60:08';
$starttime = '13:09';
$times = explode(':', $hour);
$timestamp = strtotime($starttime) + ($times[0] * 3600 + $times[1] * 60 + $times[2]);
$endtime = date('H:i', $timestamp);
echo $endtime; // 14:09
Explain:
24 = 24(hours) * 60(mins) * 60(secs)
60 = 60(mins) * 60(secs)
08 = 8(sec)
It appears like you have a start time of an activity and then a duration of how long it ran and you want to compute what's the end time. Your question becomes unclear by your use of non descriptive variable names nor any comments. You can do
<?php
$duration = "25:00:08";
$starttime = "13:09";
list($hours,$minutes,$seconds) = explode(":",$duration);
$totalTime = $seconds+($minutes*60)+($hours*3600);
$endTime = date("h:i",strtotime($starttime)+$totalTime);
echo $endTime;
?>
Sidenote: 24:60:08, 60 minutes is nothing. That's 25 hours 0 minutes and 8 seconds
If you want to get the time elapsed to process something, let's say to execute a function, you can easily do it with PHP microtime.
Assume you want to find time elapsed to execute function test, here how you do this.
public function test()
{
$time_start = microtime(true);
/*
Your code
goes here
*/
$time_end = microtime(true);
$execution_time = (($time_end - $time_start) / 60) * 60;
echo $execution_time; //This will show you the execution time in seconds.
}
If you want, you can add this seconds to any previous time stamp you saved, in order to get the execution terminated time in hh:mm:ss format. Hope this helps.
Cheers!
I am unable to understand exactly what you are looking for
<?php
$hour = "24:60:08"; // 24 hour 60 min 8 min total hour
$starttime = "13:09";
$hourArray=explode(":", $hour);
$starttimeArray=explode(":", $starttime);
$endtimearray=array();
for ($i=0;$i<3;$i++){
//Verifyng time is set else making it zero
if (!isset($hourArray[$i]))
$hourArray[$i]=0;
if (!isset($starttimeArray[$i]))
$starttimeArray[$i]=0;
$endtimearray[$i]=$hourArray[$i]-$starttimeArray[$i];
}
echo $endtimearray[0];
for ($i=1;$i<3;$i++)
echo ":$endtimearray[$i]";
Hopefully This is what you are looking for.

I am trying to add 15 minutes to given times till the end time is reached. I have been looking at loop over the time till it reaches end time with specific interval but this solution helps only for times within the same day.
In case as shown below it will not work.
$startTime = '16:00';
$endTime = '02:00';
The output I am looking for is as follow:
16:00
16:15
16:30
16:45
17:00
17:15
17...
.....
01:45
02:00
And let's say it is now 16:13 how can I then start the output from 16:30? or even better 30 mins later for example, at 16:45.
Any help is appreciated.
I think the next solution can help:
<?php
// get current time and round it to next half hour
$start = (intdiv(time(),(30 * 60)) + 1) * (30*60);
// since intdiv introduced in PHP 7 in previous PHP versoins
// intval() function can be used instead
$start = (intval(time()/(30 * 60)) + 1) * (30*60);
$end = strtotime('02:00');
// if end time less then start add one day
if ($end < $start) $end += 60 * 60 * 24;
while ($start <= $end) {
echo date('H:i',$start) . PHP_EOL;
// Increment Start date
$start += (15*60);
}

I have something like that for example: 01:06:22 this represents 1hour, 6minutes and 22seconds. I want to take that, and multiple it by 6 and add it to some other hour such as 04:23 which is 4AM and 23Minutes not 4hours and 23 minutes.
Basically, as a result I expect that:
01:06:22
* 6 = 6hours 38minutes canceling the remaining seconds which are 12 in this case
Now, I want to take that and append it to other hour, 04:23 in this case, so the result would be:
11:01.
I have no clue how to start and do it, unfortunately.
Any help is appriciated!
Clarifications
The time that I have to multiple by 6 will never exceed 2 hours.
All the times are in the same format.
With DateTime it is simple:
$time = '01:06:22';
$dateSeconds = new DateTime("1970-01-01 $time UTC");
$seconds = $dateSeconds->getTimestamp() * 6;
$interval = new DateInterval('PT'.$seconds.'S');
$date = new DateTime('1970-01-01 04:23:00 UTC');
$date->add($interval);
echo $date->format('H:i:s');
Other solution with strtotime and gmdate. (Similar to Suresh but working):
$date = strtotime('1970-01-01 01:06:22 UTC');
$add = strtotime('1970-01-01 04:23:00 UTC');
$date = (($date*6)+$add);
echo gmdate('H:i:s', $date);
This is a solution if you want to implement it yourself.
The thing about timecode is that it can become really heavy with the if the if conditions etc if you don't do it right.
The best Way I thought of to deal with this is to convert everything to second.
so 01:06:22 would become:
numberOfSecond = 22 + 06 * 60 + 01 * 60 * 60
How to get the 22, 06 etc from the String? You can use Regex.
What you will need:
a function to extract the different values (hours, minute, second)
a function to convert the timecode into second
a function to convert back into timecode
the functions to multiply, add etc...
You might want to create a class for it.
You can try like this:
$date = strtotime('01:06:22');
$add = strtotime('00:04:23');
$date = ($date*6)+$add;
echo date('H:i:s', $date);
Note: Code is not tested.
First of all you want to multiply a time span by a factor. The easiest way to do this is to convert the span to seconds and do a straight multiply:
$date =DateTime::createFromFormat('!H:i:s', '01:06:22', new DateTimeZone('UTC'));
$seconds = $date->getTimestamp();
This code works by pretending that the time is a moment during the Unix epoch start so that it can then get the number of seconds elapsed since the epoch (the timestamp). That number is equal to the duration of the time span in seconds. However, it is vitally important that the input is interpreted as UTC time and not as something in your local time zone.
An equivalent way of doing things (as long as the input is in the correct format) which is lower-tech but perhaps less prone to bugs would be
list($h, $m, $s) = explode(':', '01:06:22');
$seconds = $h * 3600 + $m * 60 + $s;
Now the multiplication:
$seconds = $seconds * 6;
If you want to only keep whole minutes from the time you can do so at this stage:
$seconds = $seconds - $seconds % 60;
The final step of adding the result to a given "time" is not clearly specified yet -- does the reference time contain date information? What happens if adding to it goes over 24 hours?
Self explanatory :
$initialTime = '01:06:22';
$timeToAdd = '04:23';
$initialTimeExploded = explode( ':' ,$initialTime );
$initialTimeInMintues = ( $initialTimeExploded[0] * 60 ) + $initialTimeExploded[1];
$initialTimeInMintuesMultipliedBySix = $initialTimeInMintues * 6;
$timeToAddExploded = explode( ':' ,$timeToAdd );
$timeToAddExplodedInMintues = ( $timeToAddExploded[0] * 60 ) + $timeToAddExploded[1];
$newTimeInMinutes = $initialTimeInMintuesMultipliedBySix + $timeToAddExplodedInMintues;
$newTime = floor( $newTimeInMinutes / 60 ) .':' .($newTimeInMinutes % 60);
echo $newTime;
Result :
10:59
My friend and I are working on a fairly basic uptime script for an IRC Bot.
Here's our code:
function Uptime()
{
global $uptimeStart;
$currentTime = time();
$uptime = $currentTime - $uptimeStart;
$this->sendIRC("PRIVMSG {$this->ircChannel} :Uptime: ".date("z",$uptime)." Day(s) - ".date("H:i:s",$uptime));
}
$uptimeStart is set immediately when the script runs, as time();
for some reason when I execute this function, it starts at 364 days and 19 hours. I can't figure out why.
Your $uptime is not a timestamp as should be used in date(), but a difference in time. You have an amount of seconds there, not a timestamp (that corresponds with an actual date.
just use something like this to cacluate (quick one, put some extra brain in for things like 1 day, 2 hours etc) ;)
$minutes = $uptime / 60;
$hours = $minuts/60 ;
$days = $hours / 24
etc
If you have 5.3 or above, use the DateTime and DateInterval classes:
$uptimeStart = new DateTime(); //at the beginning of your script
function Uptime() {
global $uptimeStart;
$end = new DateTime();
$diff = $uptimeStart->diff($end);
return $diff->format("%a days %H:%i:%s");
}
You won't get anything meaninful by calling date() on that time difference. You should take that time difference and progressively divide with years, months, days, hours, all measured in seconds. That way you'll get what the time difference in those terms.
$daySeconds = 86400 ;
$monthSeconds = 86400 * 30 ;
$yearSeconds = 86400 * 365 ;
$years = $uptime / $yearSeconds ;
$yearsRemaining = $uptime % $yearSeconds ;
$months = $yearsRemaining / $monthSeconds ;
$monthsRemaining = $yearsRemaining % $monthSeconds ;
$days = $monthsRemaining / $daySeconds ;
.. etc to get hours and minutes.
date() function with second argument set to 0 will actually return you (zero-date + (your time zone)), where "zero-date" is "00:00:00 1970-01-01". Looks like your timezone is UTC-5, so you get (365 days 24 hours) - (5 hours) = (364 days 19 hours)
Also, date() function is not the best way to show the difference between two dates. See other answers - there are are already posted good ways to calculate difference between years
Suppose the target time is 4.30 pm and the current time is 3.25 pm , how will i calculate the minutes remaining to reach the target time ? I need the result in minutes.
session_start();
$m=30;
//unset($_SESSION['starttime']);
if(!$_SESSION['starttime']){
$_SESSION['starttime']=date('Y-m-d h:i:s');
}
$stime=strtotime($_SESSION['starttime']);
$ttime=strtotime((date('Y-m-d h:i:s',strtotime("+$m minutes"))));-->Here I want to calcuate the target time; the time is session + 30 minutes. How will i do that
echo round(abs($ttime-$stime)/60);
Krishnik
A quick calculation of the difference between two times can be done like this:
$start = strtotime("4:30");
$stop = strtotime("6:30");
$diff = ($stop - $start); //Diff in seconds
echo $diff/3600; //Return 2 hours. Divide by something else to get in mins etc.
Edit*
Might as well add the answer to your problem too:
$start = strtotime("3:25");
$stop = strtotime("4:30");
$diff = ($stop - $start);
echo $diff/60; //Echoes 65 min
Oh and one more edit:) If the times are diffent dates, like start is 23:45 one day and end is 0:30 the next you need to add a date too to the strtotime.
I have a Date object ( from Pear) and want to subtract another Date object to get the time difference in seconds.
I have tried a few things but the first just gave me the difference in days, and the second would allow me to convert one fixed time to unix timestamp but not the Date object.
$now = new Date();
$tzone = new Date_TimeZone($timezone);
$now->convertTZ($tzone);
$start = strtotime($now);
$eob = strtotime("2009/07/02 17:00"); // Always today at 17:00
$timediff = $eob - $start;
** Note ** It will always be less than 24 hours difference.
Still gave somewhat wrong values but considering I have an old version of PEAR Date around, maybe it works for you or gives you an hint on how to fix :)
<pre>
<?php
require "Date.php";
$now = new Date();
$target = new Date("2009-07-02 15:00:00");
//Bring target to current timezone to compare. (From Hawaii to GMT)
$target->setTZByID("US/Hawaii");
$target->convertTZByID("America/Sao_Paulo");
$diff = new Date_Span($target,$now);
echo "Now (localtime): {$now->format("%Y-%m-%d %H:%M:%S")} \n\n";
echo "Target (localtime): {$target->format("%Y-%m-%d %H:%M:%S")} \n\n";
echo $diff->format("Diff: %g seconds => %C");
?>
</pre>
Are you sure that the conversion of Pear Date object -> string -> timestamp will work reliably? That is what is being done here:
$start = strtotime($now);
As an alternative you could get the timestamp like this according to the documentation
$start = $now->getTime();
To do it without pear, to find the seconds 'till 17:00 you can do:
$current_time = mktime ();
$target_time = strtotime (date ('Y-m-d'. ' 17:00:00'));
$timediff = $target_time - $current_time;
Not tested it, but it should do what you need.
I don't think you should be passing the entire Date object to strtotime. Use one of these instead;
$start = strtotime($now->getDate());
or
$start = $now->getTime();
Maybe some folks wanna have the time difference the facebook way. It tells you "one minute ago", or "2 days ago", etc... Here is my code:
function getTimeDifferenceToNowString($timeToCompare) {
// get current time
$currentTime = new Date();
$currentTimeInSeconds = strtotime($currentTime);
$timeToCompareInSeconds = strtotime($timeToCompare);
// get delta between $time and $currentTime
$delta = $currentTimeInSeconds - $timeToCompareInSeconds;
// if delta is more than 7 days print the date
if ($delta > 60 * 60 * 24 *7 ) {
return $timeToCompare;
}
// if delta is more than 24 hours print in days
else if ($delta > 60 * 60 *24) {
$days = $delta / (60*60 *24);
return $days . " days ago";
}
// if delta is more than 60 minutes, print in hours
else if ($delta > 60 * 60){
$hours = $delta / (60*60);
return $hours . " hours ago";
}
// if delta is more than 60 seconds print in minutes
else if ($delta > 60) {
$minutes = $delta / 60;
return $minutes . " minutes ago";
}
// actually for now: if it is less or equal to 60 seconds, just say it is a minute
return "one minute ago";
}
