Updated time zone code and data is available by anonymous ftp from elsie.nci.nih.gov (128.231.16.1) in the "pub" directory; the culprits are -rw-r--r-- 1 ado 62145 Feb 7 10:04 tzcode94b.tar.gz -rw-r--r-- 1 ado 63993 Feb 7 10:04 tzdata94b.tar.gz The updates are the work by Paul Eggert (eggert@twinsun.com) who notes:
I found another book of time zone histories by E W Whitman; it's not as extensive as Shanks but has a few goodies of its own. I used it to update the tables. I also fixed some more as a result of correspondence with Adam David and Peter Ilieve, and move some stray links from `europe' to `backward'. I corrected some scanning errors in usno1989.
As far as the code goes, I fixed zic to allow years in the range INT_MIN to INT_MAX; this fixed a few boundary conditions around 1900. And I cleaned up the zic documentation a little bit.
