Yes.  Some (not all) Windows C runtime libraries (or possibly
operating system major releases, I didn't investigate this in detail)
use a different epoch and/or don't implement the distinction between
UTC and local time correctly.   It would also be a problem if we
wanted to port to various other systems not in wide use anymore; VMS
and classic MacOS come to mind.
