Holdover occurs when the input references (GNSS, etc.) are not available and
microprocessor is steering the internal oscillator (standard, OCXO, Rubidium).
During holdover the clock accumulates error (drifts away from perfect). By adjusting
the values you can explore the relationship of holdover in days and clock error for
the installed oscillator. When the clock error is reached the server will either unlock
or revert to getting time from other NTP servers. The value obtained with this
estimator is a conservative estimate of the performance of the unit. Actual
performance may vary and will typically be better than this estimate.
Timing - Time Zone Configuration Window

Figure 4-23 below. The time zone is only for the front panel display. NTP time will
continue to be served in UTC.
