+# Stewart writes that before 1941 some companies in Bahrain were at +0330 and
|
|
# others at +0323. Reginald George Alban, a British political agent based in
|
|
# Manama, worked to standardize this, and from 1941-07-20 Bahrain was at
|
|
# +0330. However, BOAC asked that clocks be moved to gain more light at day's
|
|
# end, so Bahrain switched to +04 on 1944-01-01.
|
|
#
|
|
-# We don't know when companies chose +0330 or +0323 before 1940; for now
|
|
-# assume that there was no real standard in Bahrain before 1941-07-20.

+# It says there was no real standard in Bahrain before 1941-07-20.
|
|
+# +0330 was used by steamers of the British India Co, by Petroleum Concessions
|
|
+# and by Cable & Wireless; +0323 was used by the Eastern Bank Ltd, BOAC, and
|
|
+# Bahrein Petroleum (Bapco), and California Arabian Standard Oil Co (Casoc)
|
|
+# adopted DST effective 1941-05-24. Alban suggested adopting DST, R.B. Coomb
|
|
+# of C&W countersuggested +0330, and although C.A. Rodstrom of Casoc (formerly
|
|
+# of Bapco) stated that Bahrain had formerly used +0330 before Bapco arrived
|
|
+# but Bapco switched to +0323 because of "constant confusion", the consensus
|
|
+# was +0330. The government adopted +0330 in 1941-07-20 and companies seem to
|
|
+# have switched by 08-01. No time of day was given for the 1940s transitions.
