A filename where the date of creation or last edit is appended to the name of the document. Obviously, this information is redundant in any modern filesystem--this information is stored as metadata. However, the PrimaryKey of files in most OS filesystems is the name and only the name; use of DateStampedFilenames is intended as a workaround so <Name, Date> can be the PrimaryKey instead.
This FileNamingConvention? can be used to represent something other than the date and time the file was created or edited. It can represent an event as in 20010911.event, or a documents as in 17760704.document. Dates and times can be used as markers of more than when a file became or changed, it can be a marker of something a user or filenamer wishes to categorize or group using timeline naming.
It also can be used in DottedPrefixExtensions to further distinguish a filename, or in markers or tags to represent versions or states at a given time.
