Hi,
I have a system that allows ppl to set up and join online meetings. Currently, I just ask the guy organizing a meeting to submit his timezone and whether its in DST or not on the date of the meeting, and just show that to everyone along with the date and time of the meeting.
What I would ideally like to do, is show everyone the date and time of every meeting in THEIR timezone. I think I've pretty much figured out how to use Javascript to find out the timezone offset for a user and show him the right time. What I cant yet figure out, is to determine, given a future date for a meeting, whether that future date will have DST adjustments or not for the user's timezone.
Is there any simple way to do this, apart from hardcoding all the DST rules for all the geographies in the world into my code?
Thanks!
Ram

When using the Date object in JavaScript, the local DST settings are already applied, so it shouldn't be a problem with the offset.

I would like to set the timezone of a thread to allow me
to calculate the UTC time for data sourced from a number
of time zones. Although this can be done in C and C++, I
annot find how to do this is C#. Can this be done ? If
so how ?
Please note setting the culture does not impact the
timezone and a culture (like en-US) may have many
timezones.

Hi,
The operating system I run (Linux) comes with many, many timezone files
for many different places in the world. For example:
$ TZ='Australia/Sydney' date
Fri Oct 8 06:15:31 EST 2004
$ TZ='Europe/Amsterdam' date
Thu Oct 7 22:15:38 CEST 2004
$ TZ='Africa/Bissau' date

Hi All,
I am using pytz.common_timezones to populate the timezone combo box of
some user registration form. But as it has so many timezones (around
400), it is a bit confusing to the users. Is there a smaller and more
practical set? If not, some suggestions on how to handle the
registration form effectively would help me a lot.
thanks
Sanjay

I was investigating a function to determine whether daylight saving
was being observed on a particular date (given the platform's regional
settings) and came across a suggestion at merlyn.com to test the time
zone offset on a variety of dates to see if it changes. Based on
that, I developed the following checkDST() function which, as far as I
can tell, should be sufficient.
It checks either the date passed to it or the current date with...

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
