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. Examples: > Sys.timezone() [1] "Mountain Daylight Time" > as.POSIXct("2007-10-30 12:38:47") [1] "2007-10-30 12:38:47 Mountain Daylight Time" > # *** Should...

Hi, I'd set the daylight saving option to yes on all the GXP-2000 phones, but apparantly it doesn't move it an hour back on last sunday of October. So now I am stuck will all the phones showing the wrong time. Isn't there an option so that it'll automatically update daylight savings? Thanks -- Zeeshan A Zakari...

Hi, Normally daylight date change last sunday march for Turkey but this year daylight saving time will change for Turkey at 28 March 2011 at 03.00 AM so how can i change daylight save time setting for this year on CentOS servers ?

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 : &g...

Hello there, I have a samba PDC 3.0.0 running ok, but I had turned on the option "Time Server" in smb.conf, to synchronize the workstations time with server. But the workstations synchronize 1 hour less than it is. I think that the workstations isn?t considering the daylight saving time. I?m using the command: net time \\server /set /yes Thank?s, []?s Tercio

Hi, I am in Australian. Now it is daylight saving time in Australian. I have daysaving time issue on samba client as below.

hi there, does anyone know how to calculate the amount of daylight on every day of the year in R? I mean the time between sunrise and sunset. thanks -- View this message in context: http://r.789695.n4.nabble.com/daylight-tp4647213.html Sent from the R help mailing list archive at Nabble.com.

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 the time is set to twelve-o-clock should be an integer, regardless of which season each of the dates are in. I illu...

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

In case it hasn't been posted before, here's instructions to get the correct time to show up on your Grandstream GXP-2000's: 1. Login to phone 2. Go to Basic Settings tab 3. Change Daylight Savings Time to yes 4. Change Optional Rule to 3,2,7,2,0;11,1,7,2,0;60 (this means change clocks the second sunday of March and back again the first sunday of November - i.e., the new savings times). For additional reference, here's how to configure the 'optional rule' field from the...

Hi all, I've been having some trouble with times in regards to daylight savings in R version 2.8.1. I have an ORACLE database that R is importing data in from, for the 2am and 2:30am time intervals for the dates that daylight savings starts the times are getting read as NA values into R. I'm also finding that if I open a R workspace from version 6.2....

I've read about the 'isdst' but it is still unclear what to do. This is a cleaned up date field that I received so adjusting the date itself is not possible.

Hi. I'm running on a Windows 98 client and an RS6000 with Samba 2.0.7 (latest). I've used "net time \\ibrissde /SET /YES" to sync the times between the two systems ... but if I save a file onto the RS6000 through Samba on a mapped drive the file in UNIX is 1 hour old. I haven't been able to find any help on this so I'm assuming it's a bug !? This was also true

I have found what looks like a small problem in trunc.POSIXt() involving the transition to/from standard time and daylight savings time. Assuming my assessment is correct, I have a potential solution to offer. If a time in daylight savings time is rounded such that the rounded value is on the other side of the transition, the isdst element does not get changed accordingly. I have tested only the case of PDT round...

...e an external USB hard drive, attached to my workstation, to backup the shared data. The backup utility uses the DOS file timestamp to determine which files have changed and need to be backed up. Normally the backup takes a minute or less and only backs up a few files, but when we go on or off of daylight saving time, the backup backs up everything which takes about 5 hours. I also have some problems with my source code control system. At work we use all Windows stuff and don't have a problem. What's weird is that both Linux and XP have the correct times before and after DST, but the file...
