on 2015-02-01 at 02:00. (Thanks to Steffen Thorsen and Gwillim Law.)

Changes affecting past time stamps

Iceland observed DST in 1919 and 1921, and its 1939 fallback
transition was Oct. 29, not Nov. 29. Remove incorrect data from
Shanks about time in Iceland between 1837 and 1908.

Some more zones have been turned into links, when they differed
from existing zones only for older time stamps. As usual,
these changes affect UTC offsets in pre-1970 time stamps only.
Their old contents have been moved to the 'backzone' file.
The affected zones are: Asia/Aden, Asia/Bahrain, Asia/Kuwait,
and Asia/Muscat.
