Re: [R] Strange behaviour of ISOdatetime
Sorry for missing this part of the posting guide. It was indeed a problem with the locales. I have fixed it now.

[R] Strange behaviour of ISOdatetime

Re: [R] Strange behaviour of ISOdatetime
Have you checked that that time exists in the time zone you are using? From ?ISOdatetime: Note ... Remember that in most timezones some times do not occur and some occur twice because of transitions to/from summer time. What happens in those cases is OS-specific. You could try working out what your system is using as the transition to/from summer time. (If you need to generate times that are 2 hours after midnight, try using ISOdatetime to generate the midnight times and add 2 hours). On my system, all this works fine: ISOdatetime(1995,03,26,2,0,0) [1] 1995-03-26 02:00:00 MST ISOdatetime(1995,03,26,0,0,0) + 2 * 60 * 60 [1] 1995-03-26 02:00:00 MST sessionInfo() R version 2.8.1 (2008-12-22) i386-pc-mingw32 locale: LC_COLLATE=English_United States.1252;LC_CTYPE=English_United States.1252;LC_MONETARY=English_United States.1252;LC_NUMERIC=C;LC_TIME=English_United States.1252 attached base packages: [1] stats graphics grDevices utils datasets methods base other attached packages: [1] TimeWarp_0.7abind_1.2-0 trackObjs_0.8-0 tap.misc_1.0 [5] bmc.misc_1.0RtTests_0.1-5 -- Tony Plate Pedro de Barros wrote: Hi All, I am watching a strange behaviour of ISOdatetime.
