I can't recall ever having seen a client request
time-offset as an option, except for one VoIP
vendor.
However, I think all the common desktop OSs
handle time changes automatically as long as you
tell them the timezone when you set them up - and
will sync to a time server to get UTC.

Grandstream use it as an alternative to putting
it in a config file, but they treat 0 as -12hr
and UTC as 12hr offset. I rather suspect that
wasn't how it was intended to work.
