There are a few test cases in the date GNU test and an issue that was made about the behavior that in many use cases the -u flag is not used and the behavior of the date implementation was not matching the GNU implementation when the date is passed as stdin and when when combinations of the -u and -d were used.
The main summary of the change is that parse_date takes in Zoned now which uses the same logic for every location where a date is parsed and it will use the -u flag if it is applied. There were also issues with the logic for parsing the timezone where: "Try to parse the date with UTC first to get timestamp" was used and this causes the uutils implementation to provide the incorrect date.
Fixes: #9018
