Using Battery Backed Time On Startup - Safran SecureSync 2400 User Manual

3.2.1.4

Using Battery Backed Time on Startup

Upon system startup, by default SecureSync 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)

NOTE: Except for testing purposes, you should not choose a date
other than the current day.
Set Year Only: Some legacy time formats (e.g., IRIG) do not support
years. Checking this box will open a data entry field to manually set
the year. Safran recommends not to utilize this feature, unless the
IRIG format you are using does not provide a YEAR field.
