+# From Lee Yiu Chung (2009-10-24):
+# I found there are some mistakes for the historial DST rule for Hong
+# Kong. Accoring to the DST record from Hong Kong Observatory (actually,
+# it is not [an] observatory, but the official meteorological agency of HK,
+# and also serves as the official timing agency), there are some missing
+# and incorrect rules. Although the exact switch over time is missing, I
+# think 3:30 is correct. The official DST record for Hong Kong can be
+# obtained from
