search for: gregorian

Dear list, I will shortly have some data that contains numeric dates in the Persian / Jalali calendar format, which I would like to convert to gregorian. At the moment there doesn't seem to be a function for this in R, but it would be great if someone could come up with same - I would attempt it but the algorithm is very complex and this is also way beyond my fairly rudimentary knowledge of R. There is an informative article about how this ca...

Windows-32 has a time structure called FILETIME, a 64-bit value representing the number of 100-nanosecond intervals since January 1, 1601 (UTC). That is not a typo, the year is 1601. Does anyone have a clue(or algorhithm)for how this is converted to something a little more POSIX-like ? Thank you, Derek -- Derek N. Eder Gothenburg University VINKLA - Vigilance and Neurocognition

...om: (NULL) (85.18.136.110) >From ?as.POSIXct ## SPSS dates (R-help 2006-02-17) z <- c(10485849600, 10477641600, 10561104000, 10562745600) as.Date(as.POSIXct(z, origin="1582-10-14", tz="GMT")) ^^ It should be 15 (Gregorian calendar adoption day, when SPSS starts to count seconds behind dates) . With 14, I used a .sav dataset imported with read.spss, and after as.Date(as.POSIXct()) I got (obviously) R.date = SPSS.date - 1 Bye (and thank you for givin'us R)

Hi, are there any way to convert ISO8601 weeks to gregorian dates? Something like coverttodate(year=2006, week=38, day=1) # Sept 18, 2006 Thanks in advance, Ott

Hello all, kind regards, I have imported a data.frame from SPSS using "foreign":read.spss but unfortunately it is reading dates in a way neither R nor myself can understand. > book$DATE [1] 13502246400 13443321600 13477795200 13472956800 13501728000 13445395200 13501382400 13502851200 13444185600 13461465600 13457232000 [12] 13458096000 13432435200 13431484800 13495334400

I don't use SPSS but following through on your detective work can provide the likely answer. First note that both date numbers are evenly divisible by the number of seconds in a day, i.e. 24*60*60. This suggests that these numbers are seconds since some origin. Since we know "2003/02/11" corresponds to 13264300800 we deduce that the origin must be spss.orig <-

I have isolated what appears to be a bug in the Rails extensions to DateTime, but I don''t know where to report it. I have a standalone file to demonstrate the bug, but the punch line is that this code: TestRecord.create!(:f_datetime => (expected = DateTime.jd(2000000))) found = TestRecord.first.f_datetime puts("expected == found => #{expected == found}")

During one of my controller actions I want to call an external machine before I do anything. It''s not a real web service, more like a REST-style thing where I''ll just be tweaking a servlet running on another machine and sending it some data. Does Rails give me anything to work with for doing that? I read the web service stuff but it''s overkill for what I need. I

Dear Friends, I''d like to have a development suggestion for Rails. Rails is an amazing framework, and clearly it''s weakest link is that it relies on HTML in the end, which is not always the most appropriate GUI out there. Another option could be XUL. Mozilla-based browsers (Firefox) can run XUL apps right out of the box, others could use the XULRunner application. Here you can
