The following three calls all produce the same result (my machine is in EST):
> as.POSIXct(0, tz="", origin=ISOdatetime(1970,1,1,10,0,0))
[1] "1970-01-01 10:00:00 EST"
> as.POSIXct(0, tz="EST", origin=ISOdatetime(1970,1,1,10,0,0))
[1] "1970-01-01 10:00:00 EST"
> as.POSIXct(0, tz="GMT", origin=ISOdatetime(1970,1,1,10,0,0))
[1] "1970-01-01 10:00:00 EST"
EST is -5:00 GMT. Is it a bug that the third call above does not produce
[1] "1970-01-01 5:00:00 EST"
?
