I have a web application that displays datetime stamps on every page, for example: December 12, 2009 6:00 pm I would like to dynamically detect the user's timezone and alter the display using JavaScript. So the New York user would see: December 12, 2009 6:00 pm While the California user would see: December 12, 2009 3:00 ...
I have a windows service written in C# with .Net 3.5. It had been running on a server for a few weeks when it was discovered the that the server's timezone was not set correctly.

I am working on a Django application where I need all the postgres represented datetime fields to be saved in UTC (as they should).

Hello! I'm writting an application using Zend_Framework (so the solution can rely on it). How to get client's timezone? For example, if someone in Moscow, Russia, I want to get 3*60*60 (because there is UTC+3). If he is in UK, I want zero. If he uses UTC-3:30 (Canada?), I want -3.5*60*60. (it's not a question about a format - I'm ok ...
I'm looking for a better than O(n) algorithm to determine if a date in the future will have daylight savings time applied (and how much). Given a year, month, day, hour, minute and time zone (and a copy of the Olsen Time Zone database) how does one efficiently determine if that date will be in DST? I'm looking for the algorithm, not a ...
I have an application that stores GMT time data in a MySQL db like this: 2009-12-16 15:27:47. The user's timezone offset is stored in another column like this: -6 The above timezone is GMT-6, which is CST. Is there any way I can echo CST (i.e. - date('T")) from the GMT offset data? Note: I should also add that the application global t...

I need a way to detect the timezone of a given date object. I do NOT want the offset, nor do I want the full timezone name. I need to get the timezone abbreviation. For example, GMT, UTC, PST, MST, CST, EST, etc... Is this possible? The closest I've gotten is parsing the result of date.toString(), but even that won't give me an abbrevia...
Where can I find documentation about the binary data format outputted by javazic (the files shipped in Debian's tzdata-java package)? The standard format used in /usr/share/zoneinfo has no explicit concept of daylight savings time versus standard time. It only knows about a timezone having different offsets from UTC at different times o...
I'm implementing the Timezone support in Rails 2.1+, and I've run into an apparent bug in the way the data is pulled from the db. Let me try to set it up. The "deals" model contains an "offer_date" datetime field. Let's say I have two records with these offer_dates: Deal 1: 2009-12-29 23:59:59 -0500 Deal 2: 2009-12-28 23:59:59 -0500 ...

I just want to clarify if I am understanding how dates & time zones work. Basically, I have a date string @"2008-07-06 12:08:49" that I want to convert to an NSDate. I want this date and time to be in whatever the current user's time zone is set in. So if they are in GMT or HST, it's still 12:08:49. If I have date in unix form 12153821...

Can I configure rake tasks to be timezone aware? For e.g., can I do that following in a rake task: namespace :db do task :update_EST_records => :env...
I have a social network site I have been working on for a couple years in PHP/MySQL, I am now re-buidling the whole site from scratch again though. This time around I would really like to add in the ability for users to set a timezone for times on my site. So with that said, I am asking on a guide from start to finish of the steps I ne...
