This says nothing about civil time observed in Belize city *before* 1912; it's only an old-fashioned way to specify civil time in Belize *after* 1912.
I think a good avenue is to seek a library which has a complete collection of "The Honduras Almanack". One copy from 1829 is widely found online, e.g. http://www.columbia.edu/cu/lweb/digital/collections/cul/texts/ldpd_8627122_0... That 1829 edition says that the Belize Meridian is longitude 88 deg 02 arcmin 00 arcsec. That location likely applies to a location in Fort George, and the WGS 84 longitude for the Fort George site is about 88 deg 10 arcmin 55 arcsec, so that gives a clock difference of over 30 seconds. If such a library exists then it should give clues for the evolution of the believed coordinates of Belize. -- 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
