When parsing a timetz string with a dynamic timezone abbreviation or a timezone not specified, it was possible to generate incorrect timestamps based on a date which uses some non-initialized variables if the input string did not specify fully a date to parse. This is already checked when a full timezone spec is included in the input string, but the two other cases mentioned above missed the same checks. This gets fixed by generating an error as this input is invalid, or in short when a date is not fully specified. Valgrind was complaining about this problem.
