Question

<table class="table row-border order-column">
<thead>
<tr>
<th></th>
<?php
$days = cal_days_in_month(CAL_GREGORIAN, $month, $year);
for($i=1;$i<=$days;$i++)
{
?>
<th><?php echo $i; ?></th>
<?php
}
?>
</tr>
</thead>
<tbody>
<?php
foreach ($student as $key => $value)
{
?>
<tr>
<td class="cap"><?php echo $value->name; ?></td>
<?php
for($i=1;$i<=$days;$i++)
{
$result = $this->db->select('*')->from('attendance')->where('studentID',$value->studentID)->where('day(date)', date($i))->where('month(date)', date($month))->where('Year(date)', date($year))->get()->row();
if(empty($result))
{
$date = date('Y-m-d');
$current_date = date('d',strtotime($date));
if($i < $current_date)
{
?>
<td class="absent">A</td>
<?php
}
else
{
?>
<td></td>
<?php
}
}
else
{
$dateday = date('d',strtotime($result->date));
if($i == $dateday)

Use Unix timestamp for your calculation and after that change Unix to gmt or utc time using ready functions to show.
