U can done it by using current timestamp option.

Using NOW() or Date() you can get current system time.

<?php
$time_offset ="525"; // Change this to your time zone
$time_a = ($time_offset * 120);
$time = date("h:i:s",time() + $time_a);
echo 'Current time is : '.$time;
?>

<?php
$time_now=mktime(date('h')+5,date('i')+30,date('s'));
print "<br>".date('h:i:s',$time_now);
?>

<?php
$time_offset ="525"; // Change this to your time zone
$time_a = ($time_offset * 120);
$time = date("h:i:s",time() + $time_a);
echo 'Current time is : '.$time;
?>

<?
echo date("H m s");
?>

<?
echo date("H m s");
?>

<?php
$time_now=mktime(date('h')+5,date('i')+30,date('s'));
print date('h:i:s',$time_now);
?>

echo date("Hms");

echo date('h:i:s');

h: hours
i: minutes
s: seconds

<input type="text" value="<?php echo date('h:i:s');?>"/>

To get the local time, you have add your time zone offset.
So the function is correct.

$time_offset ="5.5"; // Asia/Kolkatta Change this to your
time zone
$time_a = ($time_offset * 120);
$time = date("h:i:s",time() + $time_offset);
echo 'Current time is : '.$time;

One another method is setting the time zone in php.ini file
or setting it in your script page using this command.

date_default_timezone_set ("Asia/Calcutta");
