I'm running into an issue where I'm unable to determine what the zone name is in cases where %s is used as the entire format string. This happens in the following zones:

After some further checking, I've noticed the same problem also applies when %s is used as part of the string (e.g. P%sT in America/Los_Angeles). For America/Los_Angeles, the switch from LMT happens in 1883, but the first rule is not until 1918. Is there a standard for these types of zones in the absence of a rule (e.g. S/D)? Thanks, Phil
