local-time: switch from time to jiff

This swaps out `time` in favor of `jiff` for getting and formatting the
local time.

Note that this does add the `%Z` to the format string, which will write
out time zone abbreviations like `EDT` along with the local datetime
itself. The `time` crate doesn't support this, but jiff's tzdb
integration let's it do it.
