The C-Bus eDLT is a switch which uses extended dynamic labelling technology. Mine are programmed to show the date and time which is sent to them by Comfort via the UCM02.

Prior to the firmware update, they displayed the same date and time as the keypads. If you did a manual setting of Comfort date/time, both the eDLTs and the keypads would show the correct date until the next auto update when the date on both would jump ahead by a day, as you are aware.

After the firmware upgrade to V2.22, the date on the keypads was correct but the eDLTs were still displaying one day ahead.

By downgrading and upgrading the UCM/ETH03 firmware, I have established conclusively that the eDLTs are no longer receiving date and time info from Comfort with V2.22 whereas they were with V2.20. Nothing else has changed apart from the firmware. Downgrading back to V2.20 results in the eDLTs being updated once again, albeit with a date that is one day ahead, which clearly points to a bug in V2.22 causing the latest issue.
