Save and restore old locale when manipulating via setlocale
We shouldn't assume a frontend program didn't explicitly set the LC_TIME setting to a value not in the environment, which is what we previously assumed. Save the old locale before forcing the 'C' locale and restore it when we are done. Signed-off-by: Dan McGee <dan@archlinux.org> Signed-off-by: Allan McRae <allan@archlinux.org>
