supported device set to MM/DD, and it will mean Dec 10 if
your supported device is set to DD/MM.
Note: Test results taken prior to the time and date being set will
not have a time and date associated with them on the meter,
and will not sync to the App. You can manually add these
readings to the App to include them in your statistics. Test results
without a set time and date will be displayed on your meter with
"--:--" and "--/--" in place of the time and date.
