Documentation

Non-nil means to check each year for DST transitions as needed.

Otherwise assume the next two transitions found after the current date apply to all years. This is faster, but not always correct, since the dates of daylight saving transitions sometimes change.

This variable was added, or its default value changed, in Emacs 22.1.
