Create a php variable storing the time one hour before the present IST time

I have converted the current UTC time to IST, and now I need to convert this time to one hour before,and store it in a variable.

<?php
date_default_timezone_set('Asia/Kolkata');

$DateTime=date('Y-m-d H:i:s'); 
$DateTime=date('H:i:s',$DateTime - 3600);//This does not seem to work 
echo $DateTime;
?>

Hope this will work.

Try this code snippet here

<?php

date_default_timezone_set('Asia/Kolkata');

$DateTime=date('Y-m-d H:i:s'); 
$DateTime=date('H:i:s',  strtotime($DateTime) - 3600);
echo $DateTime;
?>

You missed the strtotime.

strtotime will give you the unix timestamp of your date. From that timestamp, you then subtract your one hour

Referred from here

You should do date('H:i:s',strtotime($DateTime)-3600);

So, It should be 

<?php
date_default_timezone_set('Asia/Kolkata');
$DateTime=date('Y-m-d H:i:s'); 
$DateTime=date('H:i:s',strtotime($DateTime) - 3600);
echo $DateTime;
?>

Here's the eval link

For the operation you want to perform you need to use timestamp. You can not add or subtract a number from date string.

Use something like this 

$timeBeforeAnHour = date('H:i:s',time() - 3600);

This would help.
