Using Battery Backed Time on Startup

Upon system startup, by default NetClock will not declare synchronization until one of the external references becomes available and valid.

This functionality can be overridden by enabling the Synchronize to Battery Backed Time on Startup, thus allowing the battery backed time to be used as System Time upon system startup. The Battery Backed Time is also referred to as the time maintained by the integrated Real Time Clock (RTC)

This will result in NetClock providing a System Time before one of the external references becomes available and valid. This will happen automatically, i.e. without user intervention. As soon an external reference will become available, its time will take precedence over the battery backed time: The System Clock will adjust the System Time for any time difference.

Note: The Battery Backed Time is also referred to as the time maintained by the integrated Real-Time Clock (RTC).


To use the battery-backed time as the synchronized time at start-up:

  1. Navigate to MANAGEMENT > OTHER: Time Management.
  2. In the System Time panel click the GEAR icon.
  3. The Edit System Time window will display. Select the checkbox Synchronize to Battery Backed Time on Startup:
  4. Click the Submit button.
