Then use this updated option in gr-message (and nowhere else).
Items to note:
- The time format will use the same time format as determined by
preferences
- In the event that relative dates are used, the showTimeAndDate flag
will be a noop (would not want to see something like '6 months ago
4:45PM')
- Continue to not show the date and only the time when within the same
day
- All tests have been upated to test correct output wiht this option
