While compiling mush 6.4, I ran across a rather unexpected
problem during loading: "_timezone: undefined." Well I tried
"man timezone" and got the manpage for ctime(3), but timezone()
was missing from the page!

Well, we recently upgraded to UTX/32 2.1a, and an older manual
from 2.0 (which had timezone) says, "timezone may become
unsupported in a future release. Use ... is strongly discouraged."

I guess the future is now :-)

Anyhow, here is my kludge (I mean fix). Not very scientific, but
it seems to work. We are on Eastern Time, but I guess the "EST"
and "EDT" could be #define'd to any appropriate timezone.

Thanks to Mr. Heller for providing such a great tool!
