unit

- filtertype: age
  source: creation_date
  direction: older
  unit: days
  unit_count: 3

This setting must be one of seconds, minutes, hours, days, weeks, months, or years. The values seconds and minutes are not allowed with the period filtertype and will result in an error condition if used there.

For the age filtertype, or when use_age is set to True, 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)

units are calculated as follows:

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.

This setting must be set by the user or an exception will be raised, and execution will halt.
