This setting is only used with the age filtertype.

This setting is optional.

The value for this setting must be an epoch timestamp.

unit, unit_count, and optionally, epoch, are used by Curator to establish the moment in time point of reference with this formula:

point_of_reference = epoch - ((number of seconds in unit) * unit_count)

If epoch is unset, the current time is used. It is possible to set a point of reference in the future by using a negative value for unit_count.
