 # From Paul Eggert (1999-12-15):
-# For now, we'll comment out the east zone (Choybalsan)
-# and use Shanks's and the IATA's data for the daylight-saving rules.
 # Naming and spelling is tricky in Mongolia.
 # We'll use Hovd (also spelled Chovd and Khovd) to represent the west zone;
 # the capital of the Hovd province is sometimes called Hovd, sometimes Dund-Us,
 # and sometimes Jirgalanta (with variant spellings), but the name Hovd
 # is good enough for our purposes.
 
+# From Rives McDow (2001-05-13):
+# In addition to Mongolia starting daylight savings as reported earlier
+# (adopted DST on 2001-04-27 02:00 local time, ending 2001-09-28),
+# there are three time zones.
