Set the time and date
- In the Timekeeping Mode, press A: the seconds flash.
- Press C to step through the settings: seconds, hour, minutes, year, month, then day.
- On the seconds, press E to reset them to 00.
- On any other setting, press E to count up (hold for fast).
- To switch between 12-hour and 24-hour format, press D while any digits are flashing.

Good to know
Resetting the seconds between 30 and 59 adds one minute.
The day of the week follows the date by itself.
