HI, Sys.setenv(TZ="GMT") c(d) #[1] "2011-12-31 GMT" #or Sys.setenv(TZ="UTC") c(d) #[1] "2011-12-31 UTC" Hope it helps. A.K.
Yes, but c(d) will still not have a 'tzone' attribute. So the OP is okay as long as his further operations do not depend on the presence of that attribute. Peter Ehlers

Namely when function c( ) is applied to lubridate seems to change time to a local timezone in this particular case changing the date to previous one.
d<-ymd('20111231')
d
[1] "2011-12-31 UTC"
c(d)
[1] "2011-12-30 19:00:00 EST"
Is this the expected behavior and if yes, how could it be avoided for this function and the others that possibly do the same? I mean, i could create the date in my local timezone and avoid this, but if i don't do it, is there an option in environment or functions to avoid this from happening -- otherwise i need to watch out for nasty bugs.
Thanks
Andre
