2632 # From Paul Eggert (2006-03-22):
2633 # Formerly there was an America/Ensenada zone, which differed from
2634 # America/Tijuana only in that it did not observe DST from 1976
2635 # through 1995. This was as per Shanks (1999). But Shanks & Pottenger say
2636 # Ensenada did not observe DST from 1948 through 1975. Guy Harris reports
2637 # that the 1987 OAG says "Only Ensenada, Mexicali, San Felipe and
2638 # Tijuana observe DST," which agrees with Shanks & Pottenger but implies that
2639 # DST-observance was a town-by-town matter back then. This concerns
2640 # data after 1970 so most likely there should be at least one Zone
2641 # other than America/Tijuana for Baja, but it's not clear yet what its
2642 # name or contents should be.

2630 # From Paul Eggert (2006-03-22):
2631 # Formerly there was an America/Ensenada zone, which differed from
2632 # America/Tijuana only in that it did not observe DST from 1976
2633 # through 1995. This was as per Shanks (1999). But Shanks & Pottenger say
2634 # Ensenada did not observe DST from 1948 through 1975. Guy Harris reports
2635 # that the 1987 OAG says "Only Ensenada, Mexicali, San Felipe and
2636 # Tijuana observe DST," which agrees with Shanks & Pottenger but implies that
2637 # DST-observance was a town-by-town matter back then. This concerns
2638 # data after 1970 so most likely there should be at least one Zone
2639 # other than America/Tijuana for Baja, but it's not clear yet what its
2640 # name or contents should be.
2641 #
2642 # From Paul Eggert (2015-10-08):
2643 # Formerly there was an America/Santa_Isabel zone, but this appears to
2644 # have come from a misreading of
