The following table in TR-35 includes a web of fall back rules when the requested time zone style is unavailable: https://unicode.org/reports/tr35/tr35-dates.html#dfst-zone Conveniently, the subset of styles supported by ECMA-402 (and therefore LibUnicode) all either fall back to GMT offset or to a style that is unsupported but itself falls back to GMT offset.
