Lockhart would be the authority here, but I think that tz_hour/tz_minute
tell you your timezone in the form of hours & minutes west of GMT.
'timezone' gives the same info in a pure total-minutes-west style.
(There are places that run with standard time a nonintegral number of
hours off GMT, oddly enough, so you do need the minutes part.)
