Configure Timezone
Near the top of the code.py file you'll find these lines for the timezone offset:
# Set the current offset for your timezone TZ_OFFSET_FROM_UTC = -6
Update the variable with the offset from UTC for your time zone. Keep in mind that many timezones observe daylight savings time which changes their offset from UTC when daylight savings change occurs. For example the US central timezone fluctuates between -6 and -5 from UTC depending on the time of year. You will need to change this value manually, it will not account for DST automatically.
MagTag Power
This project does not aim to be low power. It is best to run the clock connected to a permanent power source rather than trying to run it off a battery. If you wanted to experiment with a lower powered battery version, you could try changing it to update only every 5 minutes or so, and to use deep sleep in between updates.
