Problem with GMT+/- time zones
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"
