If you know your offset and the offset from UTC, you can add them together and do one timezone shift. For example, if the date is at UTC+1, and you're at UTC-5, then you need to do a shift of -6 to move the date to your local timezone. However, I'd say that'll be more confusing when you have to revisit the code in a few months. Going to UTC first, and then to local will be more obvious, since you can do the string to UTC conversion in the parser, and then do the UTC to local conversion when in your application code, based on the appropriate local offset. cheers, barneyb On 8/30/05, Jim Davis <[EMAIL PROTECTED]> wrote: > > -----Original Message----- > > From: Paul Hastings [mailto:[EMAIL PROTECTED] > > Sent: Tuesday, August 30, 2005 2:12 PM > > To: CF-Talk > > Subject: Re: Timezone conversion > > > > Jim Davis wrote: > > > I'm (still) working on an ISO 8601 date parser.
