Would there be any support in this community for adding new Etc/GMT[-+] zone identifiers but with partial hours? e.g. something like "Etc/GMT-5:30"
If this happens then at the same time I would like to see the full-hour zones extended to support pre-1925 astronomical calendars which are still in use at observatories. In particular Etc/GMT+20 has been the basis of the calendar at Lick Observatory for 130+ years. -- 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
