Fair enough.  I was just trying to make what's there work consistently.

Perhaps it's good enough to remove the "-s" option from the setting
function and change back to the old format (+%m%d%H%M%Y).  I'm pretty
sure that the full-on date program will handle that, as does busybox.

Note: I think the change 41d02d40ed83c791e7a4c1d57d829d706af42e74 was
actually incorrect.  The proper change would have been to fix the
timestamp generation to be consistent.
