Subject: [R] lubridate concatenation issue
I took a look at Hadley's lubridate which seems a very neat package, but i am having a small problem with? concatenating lubridates to build vectors of it. 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
