timezones

I have a quick question regarding timezones ... On the local side a record is inserted into the DB by someone in Michigan, while the server rests in CA. Thus a three hour difference. The local mktime() will create a timestamp for say 9:00am when in reality it was entered at 12:00noon in MI. I have 2 character timezones for all my users so it should be easy to convert the two. putenv() won't work because of the fact that the timestamp created will be 9:00 no matter what timezone you put it in. So what needs to be done is some recognition that 10800 seconds needs to be added to adjust the PST timestamp to an EST timestamp. Are there any functions out ther that do this? --Joe Joe Stump <joe@joestump.net> ------------------------------------------------------------------------ One is taught by experience to put a premium on those few people who can appreciate you for what you are.
