 # (could be true), for the moment I am assuming that those two
 # counties are mistakes in the astro.com data.
 
+# From Paul Eggert (2008-02-11):
+# I just now checked Google News for western news sources that talk
+# about China's single time zone, and couldn't find anything before 1986
+# talking about China being in one time zone.  (That article was: Jim
+# Mann, "A clumsy embrace for another western custom: China on daylight
+# time--sort of", Los Angeles Times, 1986-05-05.  By the way, this
+# article confirms the tz database's data claiming that China began
+# observing daylight saving time in 1986.
+#
+# From Thomas S. Mullaney (2008-02-11):
+# I think you're combining two subjects that need to treated 
+# separately: daylight savings (which, you're correct, wasn't 
+# implemented until the 1980s) and the unified time zone centered near 
+# Beijing (which was implemented in 1949). Briefly, there was also a 
+# "Lhasa Time" in Tibet and "Urumqi Time" in Xinjiang. The first was 
+# ceased, and the second eventually recognized (again, in the 1980s).
+#
+# From Paul Eggert (2008-06-30):
+# There seems to be a good chance China switched to a single time zone in 1949
+# rather than in 1980 as Shanks & Pottenger have it, but we don't have a
+# reliable documentary source saying so yet, so for now we still go with
+# Shanks & Pottenger.
