Local time in postbit

[DRJ]

In vbulletin 3 I had the user's local time in the post bit and was using this:

GMT+$post[timezoneoffset]

I tried getting this to work in vbulletin 4 but not having much luck.

If I do {vb:raw $post[timezoneoffset]} I get a value but am not sure how to get the current time to add that value to. Also not sure about DST.

Is the user's local time a variable I can simply use for this purpose?

Thanks
