Equatorial Guinea Although Shanks says that Malabo switched from UT +00 to +01 on 1963-12-15, a Google Books search says that London Calling, Issues 432-465 (1948), p 19, says that Spanish Guinea was at +01 back then. The Shanks data entries are most likely wrong, but we have nothing better; use them here for now.
