What is the Time synchronisation in 800xA system? What are the types of it?
Also what are the trouble shooting steps to rectify time synchronisation issues?

Time synchronization means "synchronize real time clocks in an 800xA System".
To achieve the best time accuracy in the total system, it is recommended to distribute the time “upwards” in the system, from the Control Network to the Client Server Network. Typically a controller will act as time master for the Control Network and the rest of the system will be synchronized from this source.
Refer 3BSE034463-510_A_en_System_800xA_5.1_Network_Configuration.pdf - Time Synchronization section 7 (P.No 141 onwards) for more details.
Generally for 800xA nodes,check the time synch through "Time differences" tab in Time service under service structure and for AC800M nodes,check time synch through Clock synch status tool in CBM.
