    ipatests: use whole date when calling journalctl --since
    
    The test test_commands.py::TestIPACommand::test_ssh_key_connection
    is checking the content of the journal using journalctl --since ...
    but provides only the time, not the whole date with year-month-day.
    As a consequence, if the test is executed around midnight it may
    find nothing in the journal because it's looking for logs after 11:50PM,
    which is a date in the future.
    
    The fix provides a complete date with year-month-day hours:min:sec.
