Here in Australia many of our states have just kicked in to day light savings time. This involves setting our clocks one hour a head.
Unfortunately, my state doesn’t participate in this ritual, and I woke at what I thought was 4.30 am to find it was actually 3.30 am
To fix this, you need to go to the ‘Settings’ app and then select ‘General’ and select ‘Date & Time’.
If you have ‘Set Automatically’ turned on, turn this off. You will now be able to select a Time Zone.
Set your relevant time zone and then turn ‘Select Automatically’ back on.
Your phone will now keep your phone up to date an use the correct time zone.
