FMX: A time difference may occur in FMX when receiving the date and time

Created by Jean-Claude Hirzel, Modified on Wed, 25 Mar at 6:44 AM by Jean-Claude Hirzel

When receiving the date and time, a time difference (time jump) may occur in FMX.



Problem

1. If the time jump exceeds 66 seconds, the shading and the time program are restarted to avoid continuing calculations with outdated states. Because the date and time are sent separately on KNX, this can trigger restarts.
2. At the turn of the year (New Year’s Day), the ZP and BP are always restarted.



Workaround

Do not receive date and time via KNX.
