@code{getdate} was originally implemented by Steven M. Bellovin
(@email{smb@@research.att.com}) while at the University of North Carolina
at Chapel Hill. The code was later tweaked by a couple of people on
Usenet, then completely overhauled by Rich $alz (@email{rsalz@@bbn.com})
and Jim Berets (@email{jberets@@bbn.com}) in August, 1990. Various
revisions for the @sc{gnu} system were made by David MacKenzie, Jim Meyering,
-and others. The code was rewritten again in 1999 by Paul Eggert,
-to improve its support for daylight saving time.
