I couldn't find a place where that's documented but you can safely assume
that the non-localised conversion functions (i.e. the "C<Type>()" ones) are
compatible. If you want to know the format of a string to put into CDate(),
try to put a date into CStr() and see what it gives you:

  $ gbx3 -e "CStr(Now)"
  12/03/2014 17:27:48.308

and I bet the date or time part is optional and the milliseconds part alone
is also optional (didn't test).

You can implement a simple parser for your custom date formats using Scan()
and the Date() function... I'll leave that to you ;-)

Tobi
