Nokia Lumia 2520 - Why does the clock not update automatically when I travelling from one timezone to another?

Please ensure the date and time is set to automatic:

  1. Swipe in from the right to open the charms.
  2. Tap Settings.
  3. Tap Change PC settings > Time and language > Date and time.
  4. Ensure that Set time automatically is set to automatic.

Note: time will only update while on WiFi.
