          Issue ID: 15655
           Summary: SysTime.from*String incorrectly accept single digit
                    time zones and minutes > 59
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P1
         Component: phobos

"+08" and "-08" would be valid for a time zone per ISO 8601, as should be
"+08:00" and "-08:00" for the extended format and "+0800" and "-0800" for the
non-extdended format. However, strings like "+8" or "-8" are not legal. It must
be +hhmm, -hhmm, +hh, or -hh for non-extended and +hh:mm, -hh:mm, +hh, or -hh
for extended. And currently, SysTime.from*String is not properly strict about
the time zone, allowing +h and -h when there are no minutes (even though it is
properly strict when there are minutes) and is not strict about the number of
digits in the minutes. In addition, it is not strict about whether the number
of minutes is actually valid (e.g. "+07:60" should not be valid).
