We like to remind you to change your clocks on Saturday evening when you go to bed but a word of caution! Whilst you have to change all battery driven clocks there are some devices that will change time automatically – my central heating timer for one!
Also if you have an iPhone, iPad and Mac they automatically change as long as you have your 'Date and Time' settings with 'Set Automatically' turned on.
For smartphones, network operators should change the time accordingly so you shouldn't have to do anything, but make sure you have automatic updates set to your phone.
So be careful not to overdo it!
