I'm struggling with time zone version when expressed as hours offset from GMT. Can anyone confirm that the behaviour below is incorrect? It seems that the GMT offsets are backwards:
> format(as.POSIXct("2011-05-23 17:23:00", > tz="Europe/London"),tz="America/New_York",usetz=T) [1] "2011-05-23 12:23:00 EDT" - this works. > format(as.POSIXct("2011-05-23 17:23:00",tz="GMT"),tz="GMT-5",usetz=T) [1] "2011-05-23 22:23:00 GMT" - this doesn't work: 17:23:00 GMT should be 12:23:00 GMT-5! Thanks.
