Subtracting time


Recommended Posts

I've echoed these things to the screen, the first two values come from strtotime and the third is math:


last attempt time: 1286374178  (About 1:24 pm)

now: 1286735148 (About 1:25pm)

difference: 360970


What does 360970 represent? I want to know how many minutes have elapsed between the two times.

I'm not too sure that's relevant (I'm not finished with the code here, and if there's a better way I'll use it)... I really just want to know how to determine the timespan between two times. This is trivial in C#.  ;)


But since you ask...


$now = date( 'Y-m-d H:i:s' );
echo "last attempt time: " . strtotime( $di->attempt_time );
echo "<br>now: " . strtotime( $now );
echo "<br>difference: " . ( strtotime( $now ) - strtotime( $di->attempt_time ) );


where "di->attempt_time" came from a mySql datetime stamp.
