similar to: Windows 2000 Bug in GMT +/- n Timezones (PR#3644)

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.

Can anyone please shed any light on why R DateTimeClasses give weird times for when daylight saving time information changes, and which aren't consistent with the OS? Example: Expected result: in New Zealand DST stopped (NZDT -> NZST) at 03:00 NZDT on 2010-04-04, as confirmed by the OS time zone info (OS X 10.8.2): zdump -v /etc/localtime /etc/localtime Sat Apr 3 13:59:59 2010 UTC

I'm still having trouble getting to grips with time classes. I wish to calculate the difference in days between events. Browse[1]> insp.j$First [1] "2002-02-19 13:00:00 NZDT" Browse[1]> spray.j$Date [1] "2001-11-29 13:00:00 NZDT" Browse[1]> insp.jk - spray.j$Date Time difference of 82 days If I save insp.jk to a vector, I get a nice useful value of 82.

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

Hi, I have a whole bunch of data, which looks like: 15/03/2003 10:20 1 15/03/2003 10:21 0 15/03/2003 12:02 0 16/03/2003 06:10 0 16/03/2003 06:20 0.5 16/03/2003 06:30 0 16/03/2003 06:40 0 16/03/2003 06:50 0 18/03/2003 20:10 0.5 etc. (times given on a 24 hour clock) and goes on for years. I have some code:

When I say: > Sys.time() [1] "2012-11-12 21:30:14 NZDT" > But that is not what my clock on the wall and my system say.

Hello, I had been running Samba 4.8 for a few years without any problems, and then upgraded to 4.10. Since then I?ve been having problems with some accounts connecting, while some connect fine still. I haven?t been able to figure out why. My server is a relatively simple standalone server, using the LDAP password backend. A failing user authenticates OK and ends up like this in the logs:

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

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 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 have been reading the Rails recipe book and am learning a lot. One thing that I really hope makes it into rails 1.1 is an updated Timezone class that tracks daylight savings time. It seems like a shame that the Rails Timezone class doesn''t yet handle this and yet the functionality is available as a TZInfo plugin. I know the excellent calculations plugin is being brought into the rails

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

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") #

Hi, I used to upgrade/migrated samba 3.3.10 to samba 3.4.17 with LDAP backend in place, while upgrading the CentOS from 5.5 to 5.9. In place to retain the trust relationship. The users can able to login without re-authentication from existing machines. Tested 3 XPs, and 3 Win7 but it takes 5-8 mins to login compared to 1 win7 that was re-connected (disconnected from domain, restart, then rejoin

Friends I have an xts that I wish to access. Browse[2]> DATA.ba[[p]]["2012-03-20 00:59:57","bid"] bid 2012-03-20 00:59:57 1.4993 So far so good. Now putting the index into a variable: Browse[2]> Time [1] "2012-03-20 00:59:57 NZDT" Browse[2]> DATA.ba[[p]][Time, "bid"] bid Where has it gone? Looking closer....

Here's a curly one. I have a share mounted via smbfs on my linux desktop. This share is on a NetApp filer somewhere, but I've also tried this on a an old linux server as well, and I have the same problem. Basically, since day light savings came into effect here (NZDT or +13), any file I create on the share gets a time creation timestamp that is way out (approximately 12 hours and 48

Hi Aki , I need to Sieve to match the message headers TO, CC, BCC against a list of email addresses. If it gets a match, I want Sieve to set the x-original-to header to that email address (I think I can do that with Sieve extension). Is this doable? Thanks,David.

I have read the documentation, performed the diagnostic tests, checked the archives, so if the answer is there, please accept my apologies in advance and simply direct me. I am running redhat Linux 2.0.3 and using smbmount to mount several directories from NT3.51 servers which are distributed gloablly in different timezones. Once mounted the files all have local timestamps which makes syncing

This is a workaround, and could be the basis for a round.Date improvement: date <- Sys.Date() as.Date(round(as.POSIXct(date), "years")) as.Date(round(as.POSIXct(Sys.Date() + 180), "years")) Duncan Murdoch On 08/02/2024 12:23 p.m., Henrik Bengtsson wrote: > Technically, there is a round() for 'Date' objects, but it doesn't > seem very useful,
