Given Monday's mail about Syria, here are revised proposed changes to
time zone files; these changes are relative to tzdata2008a.tar.gz.

*       asia
       *       Iraq abandons DST
       *       Syria switched (from 2008 forward) to
               start DST at the start of the first Friday in April and
               end DST at the start of October 1.
       *       "Saigon" zone renamed "Ho_Chi_Minh"
*       backward
       *       backward link from "Ho_Chi_Minh" to "Saigon"
*       northamerica
       *       Change Cuba (from 2008 forward) to
               start DST the third Sunday in March.
*       southamerica
       *       Add America/Argentina/San_Luis information.
*       zone.tab
       *       Entry added for America/Argentina/San_Luis

I hope to make tzdata2008b.tar.gz available 2008-03-24.
