The fact that not all systems use the zic database.  We were tired of
random system-to-system variations in the timezone behavior ... plus we
needed functionality not exposed by the bog-standard C library API.

I've been thinking of doing that on the Red Hat distro, but the problem
is that we are now behind the curve --- we need to sync with the
upstream zic code's recently added support for 64-bit timezone files
before we can be sure of working with current system-provided databases.
I'd like to get that done for 8.3 ...
