[Rd] Date method of as.POSIXct does not respect tz

[Roland Fuß]

R 3.5.0

Is it intended that the Date method of as.POSIXct does not respect the 
tz parameter? I suggest changing as.POSIXct.Date to this:

function (x, tz = "", ...)
   .POSIXct(unclass(x) * 86400, tz = tz)

Currently, the best workaround seems to be using the character method if 
one doesn't want the default timezone (which is often an annoying DST 
timezone).
