which is
function (x, ...) .POSIXct(unclass(x) * 86400)

.POSIXct(unclass(x) * 86400, tz = tz)
or rather just forward the '...', i.e., use
function (x, ...) .POSIXct(unclass(x) * 86400, ...)
??
Then .POSIXct should gain the ellipses as an argument if you don't want
to break code that relies on as.POSIXct.Date accepting superfluous
arguments.
Btw. I think it's a bit unfortunate that as.POSIXct and as.POSIXlt don't
throw an error when passed an invalid timezone string. But that would be
more difficult to change.

Thank you Roland for your notice (and the help on SO).
Thank you and the rest of R-core for maintaining and improving one of my
work tools and my favorite programming language!
Best,
Martin
