What's microtime() ?

[Jawelin]

:cheeky:

I found a very strange behavior of the subject php function on my server.

First of all:
Linux shared running PHP v4.1.2 & MySQL v3.23.45;
GZip level 1 enabled on my pages (cheers to Nakkid... :lick: )

Well. Php page:
At the beginning, I put:

PHP Code:

$customstarttime=microtime(); 


Then, the script does a lot of actions, including a dozen of MySQL queries...
Then, at the end of the page:

PHP Code:

$customendtime=microtime();

$pageloadtime=$customendtime-$customstarttime; 


How hell $pageloadtime could be NEGATIVE, if page took almost 3-4 seconds to display, even on fast connections ???



Thanks
