Under multiple PCs environment, the time of DCU will change automatically for specific period. The time of the Server/Filemaster is correct.
Multiple PCs environment
For multiple PCs environment, the time setting of each PC doesn't synchronize. The time of Server/Filemaster is correct, but the time of Remote Client/Equalized Client may be not correct. And if there is DCU Synchronization function set on Remote Client/Equalized Client, the wrong time will synchronize to DCU for specific period set in the function of DCU Synchronization.
Synchronize the time on Remote Client/Equalized Client with Server/Filemaster through NTP or manually. The other way is only to set DCU Synchronization function on Server/Filemaster, not on Remote Client/Equalized Client.
