005 Date and Time of Latest Transaction

Field definition and scope:

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

The date and time change each time a transaction is made to the record. The latest transaction information enables an organization handling more than one version of a record to identify the most current version.

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.

Field 005 is NOT repeatable.
