$fiveMinutesAgo = time();
$fiveMinutesAgo -= 60*5;
$fiveMinutesAgo = time() - 60 * 5; // WTF @ convulted code...
I guess I could save a line of execution by doing the following
$fiveMinutesAgo = time()-60*5;
I'm sure I probably save .01 of a nano second that way.
In all seriousness tho, I find the original way easier to read when other users edited it they can quickly pick up what exacly is happening
