similar to: Rails 1.1 and Timezones

Does anyone know the best way to track time zone information. There doesn''t seem to be much documentation on this. So far it seems like a simple db field like create table accounts ( id int unsigned not null auto_increment, name varchar(50) not null, time_zone varchar(50) not null, ... primary key (id) ) and a class like class Account < AR ...

I have a number of timezone related issues which I''m currently confused about. I want to store all times in the database as UTC/GMT so that I can then massage them to be displayed how I like at a later date. I''m using the TZInfo class at the moment to convert timezones and to deal with daylight savings time. My main question is how do I ensure all data is stored as UTC when

I''m new to this list, I''m a student in History, Computerscience and a bit of Philosophy from the Netherlands... I have started using rails a few weeks ago, I did read the Agile Webdevelopment with Rails book, and I generally started to love Rails for it''s sheer beauty and intelligent structure... However I came across something that puzzles me quite a bit. It''s

Tracking down this bug was joint work with Jermoe Asselin (jerome at hivnet.ubc.ca) and Patrick Connolly (p.connolly at hortresearch.co.nz). We collectively were able to determine that this is a problem in Windows 2000 but not in Linux. Timezones of the form GMT-5, GMT+3, etc. do not work properly in Windows 2000 for nearby dates in daylight savings time although they do work for nearby dates

This is a follow-up to the thread ending with: http://rubyforge.org/pipermail/vpim-talk/2008/000120.html I too am in search of some ruby parser for icalendar which properly handles timezones on the datetimes in the icalendar RFC. As I understand it there are actually three types of times. 1) UTC times with a string form of yyyymmddThhmmssZ note the trailing Z indicates zulu time aka utc. 2)

I have some questions and comments on timezones. Problem 1. # get current time in current time zone > (now <- Sys.time()) [1] "2003-07-29 18:23:58 Eastern Daylight Time" # convert this to GMT > (now.gmt <- as.POSIXlt(now,tz="GMT")) [1] "2003-07-29 22:23:58 GMT" # take difference > now-now.gmt Time difference of -5 hours Note that the difference

Hi, I''ve been trying to do timezone conversion, and have some trouble getting it to work on my Windows machine. Searching the web, I found http://wiki.rubyonrails.com/rails/pages/HowtoSetDefaultTimeZone ...which explains how to set the default timezone. I''m using an environment.rb that include the lines: ActiveRecord::Base.default_timezone = :utc ENV[''TZ''] =

One problem with the daylight savings is that they mess with reporting tools that use timestamps. I guess an application could be configured to log UTC instead of local time, but that's not always doable. Also, if you have servers in several different timezones, it's better if all systems follow the same clock. So, I'm thinking it's perhaps better if I just use

Hello Guys, Is there any way that we can turn off DayLight saving in rails app? Rails uses tzinfo gem for converting time in zones but it does not handle it correctly for some timezone. Is there any way we can turn OFF DayLight saving completly ? Thanks -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group. To unsubscribe from

I downloaded version 0.3.12 of TZInfo from [1], and observed that it has a very robust set of timezones including, for example, ''America/ Anchorage'': irb(main):001:0> require ''rubygems'' => false irb(main):002:0> require ''tzinfo'' => true irb(main):003:0> TZInfo::Timezone.get(''America/Anchorage'') =>

Hello everyone I wonder if anyone can point me to the library for timezone management with DST support, which has timezones, like flickr has. I know that there is TZInfo, but it''s a bit different for it has huge list of available timezones in ''Continent/City'' format. I would like my application to have timezones list more like on flickr (or windows regional settings) -

Thank you very much, it was the setting on the RS6000. Whoever originally setup our box didn't specify the BST time offset correctly. The system was reading TZ=GMT0BST0,M3.5.0,M10.5.0 Thanks to everyone that contributed to solving a simple and obvious error !!!! :) Mike ________________________________________________________________________________________ >From "John Ryan"

Running under Windows XP 64 bit, as.POSIXlt()/as.POSIXct() seem to think that US time zones (EST5EDT, MST7MDT) switched from daylight savings back to standard time on Oct 28, 2007, whereas the switch is actually on Sun Nov 04, 2007.

Hi. Using this: <%= time_zone_select("account", "time_zone" %> I get a list of time zones options, like eg.: <option value="Athens">(GMT+02:00) Athens</option> But as I''m using TZInfo::Timezone, I need to map ''Athens'' to ''Europe/Athens'' I can see that the mapping I''m looking for is

Friends, So there I was, minding my own business, trying to make my rails app timezone aware (DST, as well), since it''s all about the timing with this one. There are a number of excellent articles that I''ve been working off of, in particular this one internet archived version of Scott Barron''s very useful article on the subject that is no longer available at the

I can not tell from the docs or from the mailing list what is the state of timezone support in the iCalendar package? If I want to parse an iCalendar file that has non utc dstarts and dends will it convert those times to UTC or otherwise allow me to do that? When I tried to parse an iCalendar input file started off with something like this: BEGIN:VCALENDAR METHOD:REQUEST
