Time Formula

[Anon]

Hi, I set up a time stamp into all my user accounts, each time it is accessed it saves when they last loged in, the date and the hour. I need to take that and compare it to the current date, and current hour, accounting for PM and AM.

Then I need to get how many hours there are out of that.

Please give me a formula, or a code function that would help.

The code I am writting now, is messed up, full of errors and is so large and confusing there needs to be a simpler and faster way.

The following code prints the difference in hours and minutes between 2 Unix timestamps. Modify it to suit your purposes🙂

<?php
&nbsp;&nbsp;&nbsp;&nbsp;// timestamp from 6AM, March 2nd, 2002
&nbsp;&nbsp;$dbStamp = mktime(6, 0, 0, 3, 2, 2002);

&nbsp;&nbsp;&nbsp;&nbsp;//current timestamp
&nbsp;&nbsp;&nbsp;&nbsp;$currentStamp = mktime();

&nbsp;&nbsp;&nbsp;&nbsp;// calculate difference in hours
&nbsp;&nbsp;&nbsp;&nbsp;$hours = ($currentStamp - $dbStamp)/60/60;

&nbsp;&nbsp;&nbsp;&nbsp;// get the whole and decimal portions of the $hours float
&nbsp;&nbsp;$tmp = explode(".",$hours);

&nbsp;&nbsp;&nbsp;&nbsp;// substract the hours from the float, multiply by 60 to get the minutes, and round down to 0 decimals
&nbsp;&nbsp;$minutes = floor((($hours - $tmp[0]) * 60));

&nbsp;&nbsp;&nbsp;&nbsp;// print the time info
&nbsp;&nbsp;echo "Time Difference: $tmp[0] hours and $minutes minutes<br>\n";
?>
