OS/2 and DOS AFAICT never got that option. A LAN that is a mix of LOCAL and UTC
isn't fun, especially with one or more that can't not, which is what I have with
a Linux STB providing no LOCAL option and multiple OS/2's providing no UTC
option. So I keep most on LOCAL, and reboot those that would otherwise be online
as close as I can following each change hour. Those with Windows installed I
configure to not mess with the hardware clock at change times, leaving Linux to
do the deed.

Last fresh installation that got time out of sync with hardware clock was fixed
simply with a change of /etc/adjtime from UTC to LOCAL followed by reboot.
