+ - empty: fall back to the value in /etc/adjtime, which defaults to UTC.
- "UTC": allows the operating systems to abstract away local time and ease DST.

Choose this if you dual-boot with an OS which cannot handle UTC BIOS times correctly, like Windows (note
that recent Windows versions can use UTC, which is preferable).
