    Description

      When date-time is constructed from input string bundled with date-time format (see QDateTime::fromString), in case 't' specifier is used to mandate the existence of a time zone specifier, we fail to recognize local time zone with offset. The issue got auto-resolved for UTC offsets (e.g. UTC+3) by QTBUG-83687 and related patches. However, we still miss correct handling of the matter for non-UTC prefixed time zones.

      Example:

      input       | 2008-10-13 GMT+3 11.50
format      | yyyy-MM-dd t hh.mm

      Running QDateTime::fromString() for such a pair under TZ=GMT (environment variable), results in parser only regarding "GMT" part and omitting "+3".

      Note: we need to be sane about what is supported and what is out of scope. The simple issues as the one described may and should be supported though.
