Commit 47622eef4d introduced localized times
in the metadata by way of storing the UNIX epoch value instead of a hard
coded date string. However, it missed a few things:
* If we weren't in the C/POSIX/en_US locale, the date parsing would fail
as it tried to use the abbreviations of the locale being used. Fix this
by switching the LC_TIME value before we parse a date.
* We used ctime to print the date value, which is always the C locale
string. Instead, use strftime to print a localized date string.
