similar to: Convert Rails TimeZone name to MySQL timezone name?

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

Thank you for the report. In R-devel, all.equal.POSIXt() by default reports inconsistent time zones. Previously, > x <- Sys.time() > all.equal(x, as.POSIXlt(x, tz = "EST5EDT")) would return TRUE. To ignore the time zone attributes in R-devel, the argument 'check.tzone = FALSE' needs to be used. That said, I can reproduce the 'make check' failure in R-devel on

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

So let me try to raise this issue once more, and perhaps be more clear about what I think the issue is.. In my opinion there is now a bug in make check in R-development (tested today with r79361). As I see it, I specify a reasonable TZ environment variable and this leads to make check emitting an error. Best, Kasper On Fri, Oct 2, 2020 at 11:28 AM Kasper Daniel Hansen < kasperdanielhansen

Yes, you are absolutely right and I'm pretty sure this will be fixed in one way or another. IMO, the failing test should simply use all.equal.POSIXt's new argument check.tzone=FALSE. Two simple alternatives modifying all.equal.POSIXt behaviour: - make check.tzone=FALSE the default: this is inconsistent with other arguments of all.equal methods, always defaulting to stricter checks -

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'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") #

Yes, the potential issue I see is that make check fails when I explicitly set TZ. However, I set it to be the same as what the system reports when I login. Details: The system (RHEL) I am working on has $ strings /etc/localtime | tail -n 1 EST5EDT,M3.2.0,M11.1.0 $ date +%Z EDT $ echo $TZ US/Eastern On Fri, Oct 2, 2020 at 9:48 AM Sebastian Meyer <seb.meyer at fau.de> wrote: > Thank

I have a couple questions... I am in Indiana and our time zone is changing. I used to choose America/Indiana/Indianapolis as the zone and we are changing to Eastern. Question 1) Is there a command line only way to change my timezone? I dont have access to X to run system-config-time. Doing a "system-config-time --help" or "system-config-time -h" did not give any information.

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

Dear R users, I am struggling a bit with the converting dates to full POSIX timestamps, in particular, I would like to somehow force the timezone to be local, i.e. the output of as.POSIXct(as.Date("2008-07-01")) should always be equal to "2008-07-01 00:00:00", is that achievable ? I tried to set the origin and the timezone, neither of which seems to make a difference. On my Mac

The return value of Sys.time() today with a timezone of US/Eastern is unchanged between 4.0.3-patched and devel, but on devel the following test fails all.equal(x, as.POSIXlt(x)) with x = Sys.time() This means that devel does not complete make tests (failure on tests/reg-tests-2.R) It is entirely possible that it is an error on my end, I use export TZ="US/Eastern" but I have been

Last week I started to sketch out what would be involved in building a calendar app in Rails. In the process I went looking for what Ruby has in the way of Date/Time libraries, and in particular TimeZone support. Was (pleasantly?) surprised to find that Rails seems to have Ruby''s best timezone support. But it looks like it has a very serious bug, it isn''t daylight saving

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''] =

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 , Is there anyway I can display time in “US-Central” or “US-Eastern” format instead of “ America-New york” or “ Europe-Athens” format at the top of drop down list using Tzinfo . I am presently using “time_zone_select” which displays US zones on top of drop down in “ America-New york” format . <%= time_zone_select (''profile'',

This is probably more a Ruby than a rails question, but when I call the method strftime("%Z") on a Time object, it returns the full time zone name "Eastern Daylight Time". Is there a way to get the Abbreviation instead?

Hello, I just built openssh 3.8p1 on an HP-UX 11i machine. All looks well except for the timezone. I'm noticing now that when it logs stuff to syslog, it's off by 2 hours for me. What I've figured is this: My timezone is MST7MDT (mountain time). The timezone in /etc/default/tz is EST5EDT (eastern time). There's a 2 hour difference between mountain & eastern time. What

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 both Windows 2000 and in Linux and by testing it in our three time zones that it seems to be daylight savings time related. Conversion of POSIXlt datetimes to POSIXct appears to have problems.

Greetings All, How to does one go about reconfiguring centos's time zone configuration (to the eastern time zone (us)), via the command line? I have tested other GNU/Linux distribution's documentation, tools, files and relevant details with centos and have thus far been unable to find a compatible solution. My apologies if my question is very simple, I have done a fair amount of
