which to use mktime() or gmmktime()?
 

i am not sure which is best to use when creating a UNIX timestamp for vBulletin.

mktime() expects the time being local time, gmmktime() expects it to be UTC - that's the whole difference.

Doesn't vB normally use vbmktime() ?

i didnt know there was one, can someone clarify this?

edit:
looking at calendar.php in 3.0.7, vbulletin uses gmmktime() to form its unix timestamps.

Use gmmktime when you want to give your users the right time based on what timezone they are in as opposed to the servers time :)
