similar to: get timezone abbreviation

HI, I am creating n onlinecalendar sort of functionality for which the user input for events is taken. To make it user friendly, its left to the user to write the time down rather than selecting it from a datetime field in a form . The user can also specify a timezone. And while doing so its obvious that most inputs will be an abbreviation. My question is - is there a way to convert

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''] =

I'm trying to generate POSIXct times in a call to a C function. However, I'm having trouble generating times with the proper offset from UTC. Can anyone offer any help with this issue? I've looked at R-2.0.1/src/main/datetime.c, but I was not able to find an example that I could easily pull from that file. Thanks in advance, Whit Here is my example in C: #include <stdio.h>

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)

Is it possible to get timezone abbreviations using the TimeZone or TzinfoTimezone classes? Even after converting UTC to localtime it still reports the timezone abbreviation as UTC. Example: >> @tz = TzinfoTimezone.us_zones[2] => #<TzinfoTimezone:0x30868a0 @utc_offset=-28800, @name="Pacific Time (US & Canada)"> >> @tz.now => Wed Jan 24 12:36:56 UTC 2007

Hi all, I'm having difficulty converting a 'dates' object to a POSIXct object: testDATES<-c(35947,35971,36004,36008,36053,36066) testDATES<-chron(dates=testDATES, format = c(dates = "m/d/y"), origin=c(month = 12, day = 30, year = 1899)) >[1] 06/01/98 06/25/98 07/28/98 08/01/98 09/15/98 09/28/98 > as.POSIXct(testDATES) [1] NA NA NA NA NA NA

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

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''m seeing the following in the WEBbrick console output after every GET 192.168.0.108 - - [03/Mar/2005:15:35:19 AUS Eastern Daylight Time] "GET /favicon.ico HTTP/1.1" 200 60 - -> /favicon.ico What does /favicon.ico (which doesnt seem to exist in my source) do for Rails? _______________________________________________ Rails mailing list

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

This is for Wine 1.1.28 compiled under a customised personal Linux based on Slackware. When running winefile from a terminal, get a line: "fixme:ntdll:find_reg_tz_info Can't find matching timezone information in the registry for bias -720, std (d/m/y): 5/04/2009, dlt (d/m/y): 27/09/2009" Wine source: ../dlls/ntdll/time.c holds the function "find_reg_tz_info".

Hello, I must be doing something wrong that's very obvious. But I just don't see it. I changed my Windows Time Zone to GMT and my Financial Center to Montreal. But I still get several warnings. >Sys.timezone() [1] "GMT Daylight Time" >myFinCenter [1] "Montreal" >Sys.timeDate() [1] "Montreal" [1] [2005-04-19 10:55:02] Warning messages: 1: Set

I'm having difficulties with daylight saving times in US time zones. (Apologies for the long post, but the problem seems subtle and complex, unless I'm doing something completely wrong, in which case it should be evident from the first 10 lines below.) This is what I see, using a (slightly modified) example from ?as.POSIXlt : > as.POSIXlt((d <- Sys.time()), "EST5EDT") #

Hello, i am trying to install "Middle School Success Essentials" from Topics Education, on my 0.9.28 wine installation, which works OK with some MS progs. The initial (unpacking?) progress bar completes and then i get the error below, without any recourse. Does anyone have any ideas? (FWIW, the error is shown in the installer box when you click on the "Details" button). TIA

I'm having problems entering dates and times around when daylight savings time starts. If I type (on R 1.8.1 on Gentoo Linux) > ISOdatetime(2004,4,4,0:4,0,0,"GMT") [1] "2004-04-03 19:00:00 EST" "2004-04-03 20:00:00 EST" [3] "2004-04-03 22:00:00 EST" "2004-04-03 22:00:00 EST" [5] "2004-04-03 23:00:00 EST" Giving the times

I have been playing with rsync for several weeks now, and this is the first time I have encountered this problem. Rsync is including files that haven't been updated since the last sync. In fact, it's sending every file in the folder even if it has not been updated. The current options I am using are -v -rl -e, what is causing this to happen? -- View this message in context:

Dear All, The recent improvement in RODBC to recognize datetimes in tables has exposed my ongoing confusion. All my data are obtained from a satellite system (Argos) which tags events in the GMT time zone. Daylight saving is ignored. To my way of thinking this means that 1. twelve-o-clock means halfway through the day regardless of season, and 2. the difftime of any two dates where
