    It's a known issue and basically means this timestamp value has not been set. It's equivalent of NULL for timestamps.

    Hi there,

    No, it will not delete your records.

    It's an epoch. It's the first year of the 400-year cycle in the Gregorian calendar which we were in when Windows NT was first created.

    Essentially it's an arbitrary date chosen as a starting point for calculating a number of different fields which are not stored as dates themselves.

    For the value you're looking at, Available for Scavenging Time, it's stored as the number of hours since the epoch. And in your case, the value is 0 (uninitialized).

    When it's operational it means the next time your zone can be scavenged. On the first configuration that'll be the current date plus the value of the refresh interval. It's extended by the Automatic Scavenging Interval there-after.
