 1.8  christos changes made by political bodies to time zone boundaries, UTC offsets,
 1.8  christos and daylight-saving rules.

1.14  christos This database of historical local time information has several goals:
 1.6   mlelstv
1.14  christos  * Provide a compendium of data about the history of civil time that
1.14  christos    is useful even if not 100% accurate.
 1.4       jtc
1.14  christos  * Give an idea of the variety of local time rules that have existed
1.14  christos    in the past and thus may be expected in the future.
 1.4       jtc
1.14  christos  * Test the generality of the local time rule description system.

 1.9  christos for details.
