Below find proposed relatively minor proposed changes to the time zone package:
* leapseconds: updated to reflect no mid-2009 leap second
* tz-art.htm: information on two CDs added
* zic.c: fix fencepost error
The change to zic.c will result in changed binary outputs in a handful of cases.
If no one spots problems, these changes should appear at ftp://elsie on
2009-02-08.
