 497 # It's shortly after 1:00 here on the east coast of the United States;
 498 # the staffer said it was shortly after 10:00 there. When I asked whether
 499 # that meant they were on Pacific time, they said no - they were on their
 500 # own time. I asked about daylight saving; they said it wasn't used. I
 501 # did not inquire about practices in the past.
 502 
 503 # From Arthur David Olson (2011-08-17):
 504 # For lack of better information, assume that Metlakatla's
 505 # abandonment of use of daylight saving resulted from the 1983 vote.

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.

2642 # From Paul Eggert (2015-10-08):
2643 # Formerly there was an America/Santa_Isabel zone, but this appears to
