similar to: daylight savings time difference with rspec?

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

This message, hopfully, summarizes all the questions people may have about the change affecting when Daylight Savings Time begins and ends for various time zones which takes effect this year. NOTE: Before you decide this message does not effect you please bear in mind that the most critical file involved in all of this is /etc/localtime. That is the zoneinfo file your system will be using to

I have a data frame that contains dates, but when I use as.POSIXlt() I lose the hours on all records. I traced this down to a particuar hour which causes the issue... > as.POSIXlt('2004-10-31 02:00:00') [1] "2004-10-31" > as.POSIXlt('2004-10-31 03:00:00') [1] "2004-10-31 03:00:00" How do I tell as.POSIXlt() to ignore daylight savings and just convert to

Jerry ** *---------------- * *New Federal Law?Springing Forward in March, Back in November* Months after Indiana passed the law that got it in step with the rest of the country, the federal government announced a major change in Daylight Saving Time.

The following code: cut(as.POSIXct("2009-11-01 04:00:00", tz="America/Los_Angeles"), "1 day") gives the error: Error in seq.int(0, to - from, by) : 'to' must be finite This is related to November 1st, 2009 being the switchover date from daylight savings time to standard time in the America/Los_Angeles time zone. In particular, in cut.POSIXt, the starting

I have asked this question before, and received some suggestions for work-arounds that get the job done--and they are much appreciated. But I would still like to find out if I'm missing something, and whether there is a direct way using POSIXt functions (as.POSIXct, as.POSIXlt, strptime, in particular). I have environmental data collected once per minute. Here is a subset of 3 input

OK, the code for sdivrem in APInt.h is wrong. Here's what's written: static void sdivrem(const APInt &LHS, const APInt &RHS, APInt &Quotient, APInt &Remainder) { if (LHS.isNegative()) { if (RHS.isNegative()) APInt::udivrem(-LHS, -RHS, Quotient, Remainder); else APInt::udivrem(-LHS, RHS, Quotient, Remainder); Quotient =

Under R-2.2.1, a POSIXlt date created with "strptime" has an unknown Daylight Savings Time flag: > strptime(20051208, "%Y%m%d")$isdst [1] -1 This is true on both Linux (details below) and Windows. It did not occur under R-2.1.0. Any ideas? TIA! > Sys.getenv("TZ") TZ "" Version: platform = i686-pc-linux-gnu arch = i686 os = linux-gnu

I'm searching for an r command that will notify me if I create a time that does not exist due to Daylight Savings Time. For example, if I run the following command on a windows machine > ISOdatetime(2010,03,14,2,10,0, tz = "") # My system time is set to the United States Central Time Zone [1] NA R returns NA, which is the behavior I want. However, if I run the same command on a

Colleagues, I just encountered some unexpected behavior of difftime in relationship to the change from daylight savings to standard time. My understanding is that DST and ST take effect at 2AM. However, the code below suggests that R (version 2.8.0 in OS X) implements the change at 2:16AM: Expected: > > difftime("2008-11-02 02:01:00", "2008-11-02 00:59:00")

I'm running 2.2.6 When daylight savings time changed this weekend I had to reset all samba sessions as the sessions didn't pick up the time change. Copying file from a Windows client to the server made the filetime off by one hour. Killing all the same sessions (also restarted smbd -- not sure if that was needed) fixed the problem. Michael D.

Hi, we had the same problems last year and we use NTFS. Luckely we switched to Linux this year.

This adds a bunch of static functions that implement unsigned two's complement bignum arithmetic. They could be used to implement much of APInt, but the idea is they are enough to implement APFloat as well, which the current APInt interface is not suited for.

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 6.2.2,the datetimes are

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 ...

Hi Sarath, It would have really helped if you had removed the commented out code and inlined the calls to your homemade helper functions before sending it... You are doing this, in LLVM IR: %0 = getelementptr %Value* %firstArg, i32 0 ; i8** %1 = load i8** %0 ; i8* %2 = bitcast i8* %1 to i64* %3 = getelementptr %Value* %secondArg, i32 0 ; i8** %4 = load i8** %3; i8* %5 = bitcast i8* %4 to i64*

Yeah, that's the fault...got the answer...... Thanks James for the help... Struggling with this for so many days.......
