On multiple Nook eReaders, including Nook Color or Nook Simple Touch, you can change the time by simply changing the current time zone. You can also choose between a 12-hour clock and a 24-hour clock depending on your preference. When you change your Nook eReader’s time zone, the tablet relies on the network connection to automatically adjust to the correct time. You don’t need to do anything else. Warnings Writer Bio
