Would it make sense for as.Date.POSIXct to not assume tz="UTC" if the
POSIXct object has a valid tzone attribute? Current behavior may be
confusing in certain cases, for example:
> (d <- structure(1090450800, tzone="Europe/Berlin",
+ class=c("POSIXct","POSIXt")))
[1] "2004-07-22 01:00:00 CEST"
> as.Date(d)
[1] "2004-07-21"
> as.Date(as.POSIXlt(d))
[1] "2004-07-22"
> as.Date(d, tz=attr(d,'tzone'))
[1] "2004-07-22"
Best,
