because queensland doesn't observe daylight savings. This is because the cows will become confused about milking time and also because the curtains will fade quicker... True story... http://whirlpool.net.au/wiki/dlsinqld

You would need to get the official daylight saving time tables. If you wanted historical dates, you'd need the tables that go back through the times you are storing. Josh's code is used for converting between current local times and current UTC times. For historical times, you have to determine which table to use before applying the timezone offset or you may end up using a DST offset when standard time was in effect.

Note that in .NET, the historical tables are not available, only current ones, unless you call for the time zone info structures a special way. Sorry if that's vague, but I don't recall exactly which time zone methods and classes do what.

Here is a great resource about mapping between Windows and standard time zone identifiers: Mapping from Windows Time Zone Identifiers to Standard Identifiers (http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/zone_tzid.html)

Hello Josh,

I have one question for you.I created one hidden asp control and use Javascript code to get the user timezone.I need to pass the javascript return variable value to hidden control and access in code behind cs file on page load of Infopath form.
Is there a way how it works?

Hi Josh,
Thanks a lot for posting the code.
But my problem is: I want user date/time as per user timezone or locale.

simple javascript code; var localdate=new Date(); localdate will then contain local date & timezone (as set in user's local PC, hence will be 99.99% accurate)…….for ex- Wed Jul 20 2011 22:05:42 GMT+0530 (India Standard Time) …….this can be easily parsed in standard way and used for exact timezone info…….good luck
