# Sometimes Johnston kept Hawaii time, and sometimes it was an hour behind.
770
# Details are uncertain. We have no data for Johnston after 1970, so
771
# treat it like Hawaii for now.

# <http://www.315bw.org/Herb_Bach.htm> (2005), Herbert C. Bach writes,

775
# "We started our letdown to Kwajalein Atoll and landed there at 5:00 AM
770
776
# Johnston time, 1:30 AM Kwajalein time." This was in June 1945, and
771
777
# confirms that Johnston kept the same time as Honolulu in summer 1945.
772
# We have no better information, so for now, assume this has been true
773
# indefinitely into the past.
779
# From Lyle McElhaney (2014-03-11):
780
# [W]hen JI was being used for that [atomic bomb] testing, the time being used
781
# was not Hawaiian time but rather the same time being used on the ships,
782
# which had a GMT offset of -11 hours. This apparently applied to at least the
783
# time from Operation Newsreel (Hardtack I/Teak shot, 1958-08-01) to the last
784
# Operation Fishbowl shot (Tightrope, 1962-11-04).... [See] Herman Hoerlin,
