Almost all occurrences of "daylight savings" are quotes from other
sources, and I'd rather keep them that way for the same reason that
I'd rather use British spelling when quoting British English text.

However, there's one exception: the occurrence of "daylight savings"
in date.c.  I'll add a fix in my next proposed patch.
