When input references have been supplying input to SecureSync and input from all the references
has been lost, SecureSync will not immediately declare loss of time synchronization, but first will
go into Holdover mode. While the unit is in Holdover mode, the time outputs are derived from an
internal oscillator incrementing the System Time.
Because of the stability of the internal oscillator, accurate time can still be derived even after all the
primary references are no longer valid or present. The more stable the oscillator is without an
external reference, the longer this holdover period can be and have it still maintain very accurate
