I already referred the questions in stackoverflow before posting this.
In my case I need to convert 1426023505154 to date format.To makesure the time stamp is valid I checked in http://www.epochconverter.com. I used these codes to convert. But that doesn't worked:
date_default_timezone_set('Asia/Calcutta');
$date = new DateTime();
$date->setTimestamp(1426023505154);
echo $date->format('U = Y-m-d H:i:s') ;
echo gmdate("Y-m-d\TH:i:s\Z", 1426023505154);
echo echo date('d-m-Y', 1426023505154);
But all are resulting wrong results such as:
47158-11-20 21:49:14
20-11-47158
47158-11-20T16:19:14Z
Please let me know how to solve this.
Thanks
The problem is your timestamp is in milliseconds and $date->setTimestamp uses seconds, you can fix this by dividing by 1000
$date = new DateTime();
$value = 1426023505154;
$date->setTimestamp($value/1000);
Try with -
echo date('Y-m-d H:i:s', 1426023505154 / 1000 );
// dividing by 1000 because the timestamp is in microseconds

I have a form that receives a time value:
$selectedTime = $_REQUEST['time'];
The time is in this format - 9:15:00 - which is 9:15am. I then need to add 15 minutes to this and store that in a separate variable but I'm stumped.
I'm trying to use strtotime without success, e.g.:
$endTime = strtotime("+15 minutes",strtotime($selectedTime)));
but that won't parse.
Your code doesn't work (parse) because you have an extra ) at the end that causes a Parse Error. Count, you have 2 ( and 3 ). It would work fine if you fix that, but strtotime() returns a timestamp, so to get a human readable time use date().
$selectedTime = "9:15:00";
$endTime = strtotime("+15 minutes", strtotime($selectedTime));
echo date('h:i:s', $endTime);
Get an editor that will syntax highlight and show unmatched parentheses, braces, etc.
To just do straight time without any TZ or DST and add 15 minutes (read zerkms comment):
$endTime = strtotime($selectedTime) + 900; //900 = 15 min X 60 sec
Still, the ) is the main issue here.
Though you can do this through PHP's time functions, let me introduce you to PHP's DateTime class, which along with it's related classes, really should be in any PHP developer's toolkit.
// note this will set to today's current date since you are not specifying it in your passed parameter. This probably doesn't matter if you are just going to add time to it.
$datetime = DateTime::createFromFormat('g:i:s', $selectedTime);
$datetime->modify('+15 minutes');
echo $datetime->format('g:i:s');
Note that if what you are looking to do is basically provide a 12 or 24 hours clock functionality to which you can add/subtract time and don't actually care about the date, so you want to eliminate possible problems around daylights saving times changes an such I would recommend one of the following formats:
!g:i:s 12-hour format without leading zeroes on hour
!G:i:s 12-hour format with leading zeroes
Note the ! item in format. This would set date component to first day in Linux epoch (1-1-1970)
strtotime returns the current timestamp and date is to format timestamp
$date=strtotime(date("h:i:sa"))+900;//15*60=900 seconds
$date=date("h:i:sa",$date);
This will add 15 mins to the current time
To expand on previous answers, a function to do this could work like this (changing the time and interval formats however you like them according to this for function.date, and this for DateInterval):
(I've also written an alternate form of the below function here.)
// Return adjusted time.
function addMinutesToTime( $time, $plusMinutes ) {
$time = DateTime::createFromFormat( 'g:i:s', $time );
$time->add( new DateInterval( 'PT' . ( (integer) $plusMinutes ) . 'M' ) );
$newTime = $time->format( 'g:i:s' );
return $newTime;
}
$adjustedTime = addMinutesToTime( '9:15:00', 15 );
echo '<h1>Adjusted Time: ' . $adjustedTime . '</h1>' . PHP_EOL . PHP_EOL;
get After 20min time and date
function add_time($time,$plusMinutes){
$endTime = strtotime("+{$plusMinutes} minutes", strtotime($time));
return date('h:i:s', $endTime);
}
20 min ago Date and time
date_default_timezone_set("Asia/Kolkata");
echo add_time(date("Y-m-d h:i:sa"),20);
In one line
$date = date('h:i:s',strtotime("+10 minutes"));
You can use below code also.It quite simple.
$selectedTime = "9:15:00";
echo date('h:i:s',strtotime($selectedTime . ' +15 minutes'));
Current date and time
$current_date_time = date('Y-m-d H:i:s');
15 min ago Date and time
$newTime = date("Y-m-d H:i:s",strtotime("+15 minutes", strtotime($current_date)));
Quite easy
$timestring = '09:15:00';
echo date('h:i:s', strtotime($timestring) + (15 * 60));
I need to compare bentween a time taken from a database to the current time.
$DBtime = "2013-10-29 17:38:55";
this is the format of the arrays in the database.
How can I compare it with the current time?
Im not sure how, but maybe converting DBtime to Unixtime then:
(CurrentUnixTime - dbUnixTime) = x
Or maybe, we can take the 17:38 and compare it somehow with date("G:i");
Thank you! I hope you understand what I mean.
You can transform it into a UNIX timestamp using strtotime and then subtract the current timestamp by it.
$DBtime = "2013-10-29 17:38:55";
$db_timestamp = strtotime($DBtime);
$now = time();
$difference = $now - $db_timestamp;
echo $difference;
This will give you the difference in seconds.
You can convert the DBtime string to a unix timestamp in PHP using strtotime. In MySQL, you can use UNIX_TIMESTAMP when querying the column.
time() - strtotime($DBtime)
$date1 = new DateTime('2013-10-29 17:38:55');
$date2 = new DateTime('2013-11-29 18:28:21');
$diff = $date1->diff($date2);
echo $diff->format('%m month, %d days, %h hours, %i minutes');
$DBtime = "2013-10-29 17:38:55";
// Set whatever timezone was used to save the data originally
date_default_timezone_set('CST6CDT');
// Get the current date/time and format the same as your input date
$curdate=date("Y-m-d H:i:s", time());
if($DBtime == $curdate) {
// They match, do something
} else {
// They don't match
}
I have a problem by converting a date in proper format.
I get the time the from Facebook API in this format: 2013-08-23T09:00:00
I then $fbdate = date('2013-08-23T09:00:00');
When I echo $fbdate, it retuns 2013-08-25UTC05:00:00.
Then I tried:
$datum = date("d.m.Y",$fbdate);
$uhrzeit = date("H:i",$fbdate);
To extract the date and the time but it always returns:
01.01.1970 for $datum and 00:33 for $uhrzeit.
You should use strtotime() to parse a date string into a UNIX timestamp:
$fbdate = strtotime('2013-08-23T09:00:00');
$datum = date('d.m.Y', $fbdate);
$uhrzeit = date('H:i', $fbdate);
Try using the DateTime class:
$fbdate = '2013-08-23T09:00:00';
$date = DateTime::createFromFormat('Y-m-d\TH:i:s', $fbdate);
$datum = $date->format('d.m.Y');
$uhrzeit = $date->format('H:i');
echo $datum;
echo $uhrzeit;
$datum = date("d.m.Y",strtotime($fbdate));
$uhrzeit = date("H:i",strtotime($fbdate));
The date function in PHP is meant to convert a microtime into a date, so you need to convert your string dates to microtimes first.
Have you tried this? You should use strtotime() when using the date function.
$datum = date("d.m.Y", strtotime($fbdate));
$uhrzeit = date("H:i", strtotime($fbdate));
Use strtotime()
$a = date("Y-M-d", strtotime($datum));
echo $a.$uhrzeit;

I'm not a huge fan of using timestamp.
What I did to solve this issue was:
$updatedDate = new DateTime(
preg_replace('/^(.*)\+0000$/', '$1', $fbUser->getProperty("updated_time")),
new DateTimeZone("UTC")
);
It chops the +0000 part and creates the DateTime object with an explicit UTC timezone.
I'm using a PHP script to grab data from Active Directory using LDAP..
When I get the user values for 'lastlogon' I get a number like 129937382382715990
I've tried to figure out how to get the date/time from this but have no idea, can anybody help?
Read this comment on the PHP: LDAP Functions page.
All of them are using "Interval" date/time format with a value that represents the number of 100-nanosecond intervals since January 1, 1601 (UTC, and a value of 0 or 0x7FFFFFFFFFFFFFFF, 9223372036854775807, indicates that the account never expires): https://msdn.microsoft.com/en-us/library/ms675098(v=vs.85).aspx
So if you need to translate it from/to UNIX timestamp you can easily calculate the difference with:
<?php
$datetime1 = new DateTime('1601-01-01');
$datetime2 = new DateTime('1970-01-01');
$interval = $datetime1->diff($datetime2);
echo ($interval->days * 24 * 60 * 60) . " seconds\n";
?>
The difference between both dates is 11644473600 seconds. Don't rely on floating point calculations nor other numbers that probably were calculated badly (including time zone or something similar).
Now you can convert from LDAP field:
<?php
$lastlogon = $info[$i]['lastlogon'][0];
// divide by 10.000.000 to get seconds from 100-nanosecond intervals
$winInterval = round($lastlogon / 10000000);
// substract seconds from 1601-01-01 -> 1970-01-01
$unixTimestamp = ($winInterval - 11644473600);
// show date/time in local time zone
echo date("Y-m-d H:i:s", $unixTimestamp) ."\n";
?>
This is the number 100-nanosecond ticks since 1 January 1601 00:00:00 UT.
System time article in Wikipedia can give you more details.
What about this:
$timeStamp = 129937382382715990;
echo date('Y-m-d H:i:s', $timeStamp);
EDIT ------
I just tried the following and noticed that this method wont work unless the clock on your machine is set 10 years in the future. Below is the code I used to prove the above pretty much useless unless you do more processing maybe..
$time = time();
echo date('Y-m-d H:i:s', $time);
echo "<br />";
$timeStamp = 129937382382715990;
echo date('Y-m-d H:i:s', $timeStamp);
In my case I'm using Pentaho. With a Modified Javascript value you can convert the values, lastLogon is the column I wanna convert from data stream:
calendar = java.util.Calendar.getInstance();
calendar.setTime(new Date("1/1/1601"));
base_1601_time = calendar.getTimeInMillis();
calendar.setTime(new Date("1/1/1970"));
base_1970_time = calendar.getTimeInMillis();
ms_offset = base_1970_time - base_1601_time;
calendar.setTimeInMillis( lastLogon / 10000 - ms_offset); //lastLogon is a column from stream
var converted_AD_time = calendar.getTime(); // now just add this variable 'converted_AD_time' to the 'Fields' as a show in the image below
I used :
<?php
echo date("H:i:s", $var_time_diff);
?>
to construct a time between two dates.. and in my head it was
$var_time_diff = 36000 = display 10:00:00 for 10 hours.
But in fact
<?php echo date("H:i:s", 0);?>
display 01:00:00 and not 00:00:00.
So we have
$date_a = "18:15:04";
$date_b = "23:15:04";
$diff = strtotime($date_b) - strtotime($date_a);
All is ok for the moment $diff is 5 hours but if we display date like this:
echo date("H:i:s", $diff);
it will be "06:00:00".
So something wrong with my php config or it's a normal behavior for php function date?
The date() function uses your current time zone. If you want to ignore your configured time zone, use date_default_timezone_set() or use gmdate().
You're in some timezone other than UTC. Try:
<?php
date_default_timezone_set('UTC');
echo date("H:i:s",0) . "\n";
I'm not sure why, but date outputs the current hour in your example, make a timestamp from your seconds first and it works. I'll be following this question for a deeper explanation though.
$date_a = "18:15:04";
$date_b = "23:15:04";
$diff = strtotime($date_b) - strtotime($date_a);
echo date("H:i:s", mktime(0,0,$diff));
edit: ah, so it adjusts to your current timezone, so does mktime, so the effect is negated.
use mktime, and min 1 for hour # $diff
