The inverter gets the time from the router. The router is stuck on GMT, how do I change it onto british summer time? Thanks!</P><P>&nbsp;</P> Sun, 15 Oct 2023 09:07:58 GMT https://community.bt.com/t5/BT-Devices/Change-the-router-clock-to-daylight-savings-time/m-p/2320352#M30929 sirrahking 2023-10-15T09:07:58Z Re: Change the router clock to daylight savings time https://community.bt.com/t5/BT-Devices/Change-the-router-clock-to-daylight-savings-time/m-p/2320360#M30930 <P>The router and your devices actually store and exchange timestamps in UTC (Coordinated Universal Time - I know!) and it's down to individual devices (such as the inverter) to add their offsets based on their own locale settings.</P><P>That the inverter is not taking account of the change from BST to GMT is more an issue with the inverter software.&nbsp; You can't change the setting of UTC on the router, but if you did then nothing else on your network would work - and you'd be totally without internet.&nbsp; The internet runs on UTC not local time!</P> Sun, 15 Oct 2023 09:24:30 GMT https://community.bt.com/t5/BT-Devices/Change-the-router-clock-to-daylight-savings-time/m-p/2320360#M30930 Crimliar 2023-10-15T09:24:30Z
