+ # 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

I think you want to remove "Kemerovskaya oblast'," from the description 
of the Asia/Krasnoyarsk zone (line 2077 in tz2009p); or, if you want to 
keep Oscar's comment intact, add a comment indicating that Kemerovskaya 
oblast' is now dealt with in Asia/Novokuznetsk.
