Date accessioned

Date accessioned records the date a collection was first registered in a managed environment such as a repository. It is an indication of the currency of a metadata record.
This information answers the question: When was the metadata record describing this collection first accessioned into its source repository?

RIF-CS best practice guidelines

This date is the date a collection was accessioned into its source system, not the date it was registered in the ANDS Collections Registry.

This date will be provided to the ANDS Collections Registry as part of a RIF-CS document. It is not derived from other data.

Date accessioned can only be used for registry objects that describe collections.

Dates are described in UTC and are one of the forms described in section 3.2.7 of the W3C's Schema Data Types document. See also background information about dates and times.

Accession dates will usually be system-generated by the source system.

Dates are stored with time zone information. When a time zone is added to a UTC dateTime, the result is the date and time 'in that time zone'. For example, 2002-10-10T12:00:00+05:00 is described as 2002-10-10T07:00:00Z and 2002-10-10T00:00:00+05:00 is described as 2002-10-09T19:00:00Z.
