+# From Hideyuki Suzuki (1998-11-16):
+# The ordinance No. 51 (1886) established "standard time" in Japan,
+# which stands for the time on E 135 degree.
+# In the ordinance No. 167 (1895), "standard time" was renamed to "central
+# standard time".  And the same ordinance also established "western standard
+# time", which stands for the time on E 120 degree....  But "western standard
+# time" was abolished in the ordinance No. 529 (1937).  In the ordinance No.
+# 167, there is no mention regarding for what place western standard time is
+# standard....

+# I wrote "ordinance" above, but I don't know how to translate.
