[tz] Some time zone history (1)

[P Chan]

Defence (Time Determination Ordinance Amendment (No.2)) Regulations, 1942 <https://books.google.com/books?id=Das-AQAAIAAJ&pg=PA87> also repeal DST. Therefore it should be GMT+0:30 from 1942-02-08 to 1946-01-05 all-year. This can be confirmed by The Crown Colonist, Volume 12 (1942), p 453 <https://books.google.com/books?id=nJAeAQAAMAAJ&pg=PA453> which says "G.C. Time.—It is now learned that no further change in Gold Coast standard time is likely, and the present time, half an hour ahead of Greenwich, has been confirmed throughout the whole year."
