Hi Rodrigo,
Thanks for the reply.
I don't think there is anything wrong with it. I am just trying to see if
there is a way I can tell it to assume IST and not GMT since there are 2
such times due to DST i.e.
1. 2007-10-28 01:20:00 IST and
2. 2007-10-28 01:20:00 GMT.
Is there a way I can do this using the DateTimeFormatter? e.g. is there a
way to do the following:
DateTimeFormatter.parse("2007-10-28 01:20:00 IST") or perhaps
DateTimeFormatter.parse("2007-10-28 01:20:00 UTC+1")
or something like that?
thanks,
- Paul.
