Where this clock belongs

Notes from the time database
The story behind the clock
These source notes describe a period or rule. They do not, by themselves, establish a causal claim for a particular clock change.
Shanks & Pottenger say AT is 2:00, but IATA SSIM (1991/1997) says 1:00s. Go with IATA.
Original IANA source file: northamerica.
