+# the library doesn't seems to have any record stored about press during that
+# period of time. Some media resumed publication soon after that within the
+# same month, but there were not much information about time there. Later they
+# started including a radio program guide when they restored radio service,
+# explicitly mentioning it use Tokyo standard time, and later added a note
+# saying it's half an hour ahead of the old Hong Kong standard time, and it
+# also seems to indicate that Hong Kong was not using GMT+8 when it was

# For a map of Indiana's time zone regions, see:

+# A brief but entertaining history of time in Indiana describes a 1949 debate
+# in the Indiana House where city legislators (who favored "fast time")
+# tussled with farm legislators (who didn't) over a bill to outlaw DST:
+# "Lacking enough votes, the city faction tries to filibuster until time runs
+# out on the session at midnight, but rural champion Rep. Herbert Copeland,
+# R-Madison, leans over the gallery railing and forces the official clock
+# back to 9 p.m., breaking it in the process. The clock sticks on 9 as the
+# debate rages on into the night. The filibuster finally dies out and the
+# bill passes, while outside the chamber, clocks read 3:30 a.m. In the end,
+# it doesn't matter which side won. The law has no enforcement powers and
+# is simply ignored by fast-time communities."
+# How Indiana went from 'God's time' to split zones and daylight-saving.

+# A brief but entertaining history of time in Indiana describes a 1949 debate
+# in the Indiana House where city legislators (who favored "fast time")
+# tussled with farm legislators (who didn't) over a bill to outlaw DST:
+# "Lacking enough votes, the city faction tries to filibuster until time runs
+# out on the session at midnight, but rural champion Rep. Herbert Copeland,
+# R-Madison, leans over the gallery railing and forces the official clock
+# back to 9 p.m., breaking it in the process. The clock sticks on 9 as the
+# debate rages on into the night. The filibuster finally dies out and the
+# bill passes, while outside the chamber, clocks read 3:30 a.m. In the end,
+# it doesn't matter which side won. The law has no enforcement powers and
+# is simply ignored by fast-time communities."
+# How Indiana went from 'God's time' to split zones and daylight-saving.
