I don't, but the computer does.

There was a fair amount of mod.std.unix posting in early '86, kicked
off by

Mark Horton's original "How best to handle time conversion?"

Bob Devine responded since he'd been responsible for time stuff with

earlier employer; he was person who knew that astrologers had the

information about DST in the past.

Robert Elz was motivated by the fact that
the Australian government fiddled

the DST rules down there for a visit by the
Queen in March of '86.

He boldly installed the early code just before the

Robert's changes to "date" to work with the new functions showed up

mod.sources in June of '86.

Robert knew of your work before I did:

Clearly the mods had been sent by the time

the "timezone mailing list" was announced in late '86:

(How it is that I forgot after then how to spell
compatibility is beyond me.)

The mailing list saw a flurry of activity in
December of '86, with an upcoming

P1003 meeting due to try to figure out how to
standardize time conversion;

H-P was preparing an alternative proposal to
"P.55," which was based on the

table-driven stuff.  As part of the flurry, John
S. Quarterman

(who carried the banner before P1003) got involved at kre's

There's a mailing list at elsie for tz discussions.

Bradley White first appears
(at least in my back mail files) in early '87:

(presumably after the P1003
meeting?); he was referred by. . .
