Hi! > # This data is by no means authoritative; if you think you know better, > # go ahead and edit the file (and please send any changes to > # tz(a)elsie.nci.nih.gov for general use in the future). I am sending modifications to the Argentinian time zone table... please check comments below to find out the source used. We did three modifications: * The table was completed for the missing years 1989-1993. * The name of the time zone was changed from America/Buenos_Aires to Argentina/Buenos_Aires * The (short) names where changed from E%sT to AR%s (AR was chosen because they are the ISO letters that represent Argentina). --- 8< ----------------------------------------------------------- ############################################################################### # Argentina # From Bob Devine (January 28, 1988): # Argentina: first Sunday in October to first Sunday in April since 1976. # Double Summer time from 1969 to 1974.

I've been distributing your tz* packages in a utility package for the Linux community (util-linux). Although I distribute the files freely (some are under the GNU GPL, so they must be distributed with sources), sometimes the package is included on a commercial CDROM (I don't have any control over this). I was going over the copyright notices of the packages in util-linux, and I could not find any notices in the tz* packages which says anything about redistribution restrictions: some files are under a freely distributable UCB license, but others are not. I wanted to check with you to make sure that redistribution (even commercial redistribution) is ok. Thanks for your help in this matter. Let me know if I can provide more information about anything or if I can clarify any of my questions.
