It's not the syntax as much as the timezone.

Well, that's part of the overall syntax, or structure
	at least.

But what has as.Date done wrong, since you seem set on ignoring it?

It's not that I'm ignoring it --- it's just that I haven't a
	clue what it means/does.  The help on the date/time stuff is
	totally opaque.  It appears to be meaningful only to those
	who are already completely au fait with the ``POSIX''
	standards (whatever they are!), and thereby are not in need
	of help.  (Reminds me of Sam Johnson's ``Letter to Lord
	Chesterfield'', but that's another story.)

	Anyhow, I found that all I could do was to proceed by trial
	and error, using all possible permutations and combination of
	strptime(), as.POSIXct(), as.POSIXlt(), format(), etc. etc.
	I actually did use a few perms and combs involving as.Date()
	--- but clearly not enough of them.

as.Date(z) - as.Date("1999-12-31")

Time difference of 102 days

That is exactly the syntax that I need, it would seem.

	Thank you!
