GM time vs. local time

[Pig]

I'm handling some date manipulations, and I found my numbers were way off. I did a test, and got some weird results.

I'm running this off my local machine, which is set to Pacific Standard Time (both the time, and the region). I created this test:

				//get GMT timestamp
				$GMTstamp = gmmktime();

			//get local timestamp
			$testLocalStamp = mktime();

			//calculate diff between local and and GMT timestamp				
			$testdiff = $testLocalStamp - $GMTstamp;

			//extract time format from timestamp, and print it
			$testdifftime = strftime("%Y.%m.%d...%H:%M.%S", $testdiff);
			echo($testdifftime);

My understanding, is that $testdifftime should end up being Jan 1st, 1970 @ 8:00. (because of the nix timestamp) Thus indicating a time diff of 8hrs between PST and GMT.

What I get instead, is Jan 1st, 1970 @ 1:00... indicating 1 hour difference between server and GMT.

Am I missing something, because I sure feel like I am.

Thanks for the help.

Err why are you getting GMT time and local time than subtracting them

Because of the issues I was having. I was pulling GMT, modifying it get different regional times, but GMT was coming up wrong from what I new it should be.

I created this to test what the computer thought the diff was between me and GMT.
