T-GM uses the MaxInSpecOffset value to determine the state change from HOLDOVER to FREERUN. By default, HoldoverTimeout is set to 14,400 seconds, LocalMaxHoldoverOffset is 1,500 ns, and MaxInSpecOffset is set to 100 ns. With this configuration, the holdover state times out in 16 minutes due to the slope increment occurring every second, reaching MaxInSpecOffset of 100ns within 16 minutes.E810 support 4 hours of holdover and to keep this behavior consistent need to set default MaxInSpecOffset to 1500
 
These values should be configurable by end-users and allowed to be different in the cluster-compare templates, but default to the values below:

     LocalMaxHoldoverOffSet: 1500 LocalHoldoverTimeout: 14400 MaxInSpecOffset: 100 

     LocalMaxHoldoverOffSet: 1500 LocalHoldoverTimeout: 14400 MaxInSpecOffset: 1500
