 # President Eduard Shevardnadze decreed Wednesday.

+# From the BBC via Joseph S. Myers (2004-06-27):
+#  	
+# Georgia moved closer to Western Europe on Sunday...  The former Soviet
+# republic has changed its time zone back to that of Moscow.  As a result it
+# is now just four hours ahead of Greenwich Mean Time, rather than five hours
