atime values and retention settings have these general correspondences:

  • atime values in the future correspond to specific retention settings in the future.
  • atime values more than 24 hours in the past correspond to retention settings that prevent deletion.
  • atime values 24 hours or less in the past correspond to retention settings that permit immediate deletion.

The table below shows the effects of valid atime changes on retention settings for an object with atime synchronization in effect.

Changing the atime value to When the current retention setting is Changes the retention setting to
A time later than the current date and time Initial Unspecified (-2) or Deletion Allowed (0) The new time of the atime attribute
A time later than the current retention setting A specific date and time The new time of the atime attribute
A time more than 24 hours before the current date and time*

Initial Unspecified (-2), Deletion Allowed (0), or

a specific date and time

Deletion Prohibited
A time 24 hours or less before the current date and time* Initial Unspecified (-2) or Deletion Allowed (0) The new time of the atime attribute, which immediately makes the object expired and deletable
*Twenty-four hours is the default setting for this threshold. If you want it changed, please contact your tenant administrator.

The table below shows the effects of valid changes to retention settings on atime values for an object with atime synchronization in effect.

Changing the retention setting to When the current retention setting is Changes the atime value to
A time later than the current date and time Initial Unspecified (-2) or Deletion Allowed (0) The same time as the new retention setting
A time later than the current retention setting A specific date and time The same time as the new retention setting
A time before the current date and time Initial Unspecified (-2) or Deletion Allowed (0) The same time as the new retention setting
Deletion Allowed Initial Unspecified (-2) January 1, 1970 00:00:00 GMT
Deletion Prohibited

Initial Unspecified (-2), Deletion Allowed (0), or

a specific date and time

The current date and time minus the threshold beyond which atime sets retention to Deletion Prohibited*
*Twenty-four hours is the default setting for this threshold. If you want it changed, please contact your tenant administrator.

If atime synchronization has already been triggered for an object and the object is under retention, you cannot use atime to change its retention setting while HCP is configured to disallow permission changes for objects under retention. However, you can modify the setting in retention.txt, and, when you do so, the atime value is synchronized with the new retention setting.
