No, valid names are the names of time zones in the zoneinfo database. There
isn't really any usecase for defining up your own rules as that would mean
that you want a time zone that doesn't exist, which seems a bit pointless.

(We have KeyError rather than UnknownKeyError, NameError rather than
> UnknownNameError, etc.)

Sure, but what would otherwise a KeyError be unless an unkown or
non-existing key?
