Daylight saving time misspelling

[kurtmckee]

In wp-admin/options-general.php, daylight saving time is incorrectly referred to as "daylight savings time". Additionally, there are inconsistencies with its capitalization in the file.

I have not found any authoritative information on its capitalization, so in the attached patch against trunk (as of 14 Feb 2009) I not only corrected the misspelling, I also normalized all references to be entirely lowercase, in keeping with the predominant capitalization already in the file.

I'm fairly certain that correcting this will affect translations.

Assumed it's a trunk patch.
