Field definition and scope:

Field 005 contains 16 characters that specify the date and time of the latest transaction made against any field in a separate holdings record.  The date and time serve as a version identifier for the record.  They are recorded according to Representation of Dates and Times (ISO 8601).

The date requires 8 numeric characters in the pattern yyyymmdd (4 for the year, 2 for the month, and 2 for the day).

The time requires 8 numeric characters in the pattern hhmmss.f (2 for the hour, 2 for the minute, 2 for the second, and 2 for a decimal fraction of the second, including the decimal point).  The 24-hour clock (00-23) is used.

The date on which a record is first entered into machine-readable form is contained in field 008/00-05 (Date entered on file).  The Date entered on file never changes.  The date on which the holdings statement was last updated is contained in field 008/26-31 (Date of report).

Field 005 is NOT repeatable.

Guidelines for applying content designators:

Field 005 has no indicators or subfield codes.
