Draft: "Please select the offset corresponding to your time zone. Contrary to UTC, positive values to GMT refer to zones west to Greenwich and negative values to east to Greenwich (e.g. UTC-6 = GMT+6). Time zone: GMT, GMT+0, GMT+1, ..., GMT-9, Greenwich, UCT, UTC, Universal, Zulu".
Because of its defining expression UT has been departing from GMT for 120 years, but the difference remains inconsequentially small. The wording above will get more complicated by mid 21st century as UTC deviates notably from GMT. -- Steve Allen <sla@ucolick.org> WGS-84 (GPS) UCO/Lick Observatory--ISB 260 Natural Sciences II, Room 165 Lat +36.99855 1156 High Street Voice: +1 831 459 3046 Lng -122.06015 Santa Cruz, CA 95064 https://www.ucolick.org/~sla/ Hgt +250 m
