Sbtract time from date

[ghjk]

I want to subtract three hours from current time. How can i do that?

That depends.
Can be as simple as:
[code=php]
$newDate = date("H:i:s", time() - (3600 * 3));
[/code]
If this is not what you need, please explain in greater detail, and show us the code you are using.
