Hi,
The time zone is encoded in the string at the end e.g
Mon, 11 May 2009 18:24:37 +1200
Is in a time zone that's +12 (12 hours ahead of utc)
DateTime.parse or Time.parse will read this correctly.
So what you're doing is using a js date picker that gives you a string
like "Mon May 11 18:24:37 2009"
You just need to append the time zone difference to "Mon May 11
18:24:37 2009 +1200" etc before parsing.
I handle storing dates in the db a little differently than you, but if
you know what you're doing don't worry about changing that part.
I usually store dates in the db in utc format (I think you can
configure this in environment.rb from memory), and you can easily set
the user's timezone in a filter in application controller
Time.zone = user.time_zone
which will handle all of the conversions for you.
Cheers,
Jeremy
