If you installed the 9.2.0 test build linked above please do a manual upgrade to the now released official 9.2.0 version (from the download page).
Further to my post above (Saturday 0952), I disconnected the ethernet adapter (no wifi) and checked the RTC on switch on at 17:52 today (Wednesday) and the RTC was correct. So I can confirm the changes made 'blind' by HiassofT works fine
Thanks for your help in maintaining an up to date image for the Slice CM 1 and CM3 boxes. It is appreciated!!
