Texas timezone history
I have reviewed the Texas timezone history before 1970. I attach my result, which proposes two additional Texas zones America/Houston and Amerca/Amarillo. I think there is an error in the current tzdata/northamerica file regarding Texas. It claims that Texas follows America/Chicago. But this is not the case as Texas had no DST in 1936, as Chicago did. Please check my data and my typing, as I am a bad typist.

Typically when there's a comment to that effect in the tz database, it's referring only to time stamps starting with 1970. If you go back far enough, every city, town, and village had its own little time zone, and the tz database does not attempt to cover that. Its coverage of time stamps before 1970 are only for locations that have differed after 1970.
ok, got it, thanks On Thu, Sep 8, 2011 at 10:14 PM, Paul Eggert <eggert@cs.ucla.edu> wrote:
