unixtime and timezone differences?
 

When displaying a date to a user, I know vbdate() will offset according to a user's timezone, however what would I use when I want to offset a unix timestamp according to the user's timezone within the execution of a script?

Do you know the user's timezone in your custom script? If so - you could just add the seconds on to the timestamp before formatting it. (e.g. user with +2.5 hours = TIMESTAMP + (2.5*60))

I suppose I could gather the user's timezone difference like this:

$tzdiff = $vbulletin->userinfo['timezoneoffset']

then either increase or decrease the unixtimestamp appropriately, however I would have figured that vbulletin has a function already set up to handle something like this.

I looked all through the API and couldn't find one that handled unixtime, only display time. This is somewhat surprising considering the fact that `dateline` is is used so often in post, thread, user tables etc...

When dates are displayed, they are run through vbdate(), meaning all offsets are already handled. The "stored" Unix timestamp is always UTC.

correct - vbdate() handles display time, however I was expecting a function to handle just the unixtime. The code you provided above is simple enough, I will just use that and it should suffice - thanks again Dismounted!

the reason i am trying to offset the timestamp is because I am attempting to write a calendar search modification, and the events will need to be searched for using unixtime, as offest to the user's timesone.
