tzcode2002a.tar.gz and tzdata2002a.tar.gz

The files ftp://elsie.nci.nih.gov/pub/tzcode2002a.tar.gz and ftp://elsie.nci.nih.gov/pub/tzdata2002a.tar.gz are now available. These include the changes circulated on the time zone mailing list last week by Paul Eggert, an update to the "leapseconds" file to note that there'll be no leap second at the end of June, 2002, a change to "zic.c" to deal with a problem in handling the "Asia/Bishkek" zone, and a change to "difftime.c" to avoid sizeof problems. Changes to data for Argentina await settling of dust. --ado
