Because the zones are out of normal scope for the 22309576Sglebius# database, less effort is put into maintaining this file. Many of 23309576Sglebius# the zones were formerly in other source files, but were removed or 24309576Sglebius# replaced by links as their data entries were questionable and/or they 25309576Sglebius# differed from other zones only in pre-1970 time stamps. 26309576Sglebius 27309576Sglebius# Unless otherwise specified, the source for data through 1990 is: 28309576Sglebius# Thomas G.
