Hello Ana (and Heitor),
Please note that at the current time, the list command is generic, and
thus it only knows how to print character strings that have been
returned by the SQL engine. Though there may be some way to tell SQL
that the result we get for expiresin is a "duration" (note: very
different from a date such as LastWritten), I do not know how to do it.
Thus for the moment, we are limited to displaying SQL generated
character strings in the form that SQL gives them to us.
The main point of the new expiresin field is that it is not zero, the
retention period has not expired. If it is a big positive number
(number of seconds remaining before the volume expires), then the Volume
will not be recycled.
Many people forget that the retention period *begins* from the
LastWritten time, which means that as long as you are writing on the
Volume, nothing will be expired. Maybe devoting a bit of thought to
that particular point, and what would happen if we changed it, would
make retention periods easier to understand.
Best regards,
Kern
