Certain apps that have live events require your device's clock to be synchronised with the country the app contents supposed to be in.
For example, to access BBC ONE Live streaming from the Android BBC iPlayer app, you will need to change your device timezone ie time & date settings to match that of the UK.
This is sometimes required for some apps that checks on your device timezone regardless of whether the programme is LIVE or Catchup.
To do this on an iOS device, please follow the steps below:
1) From your device homescreen, tap on Settings followed by General
2) Now click on Date & Time.
3) Turn off Set Automatically
4) You should now be able to set the timezone to the one that you desire.
