FIELD DEFINITION AND SCOPE

Six numeric characters, in the pattern hhmmss, that represent the playing time for a sound recording, videorecording, etc. or the stated duration of performance of printed or manuscript music. If the playing time is less than 1 hour, the hour (hh) is recorded as two zeroes; if less than a minute, the minute (mm) is also recorded as two zeroes.

Playing time may also be recorded in natural language in a note (field 500 and/or 505) or in field 300 (Physical Description).

If the complete playing time is recorded in the physical description area (field 300, subfield $a) and the playing time of the parts are recorded in the contents note (field 505), field 306 should contain either the playing time of the whole or the playing time of the parts, whichever is deemed more useful.
