This HowTo explains how to easily reformat a duration value in seconds (or nanoseconds, microseconds, etc) into an ISO8601 duration.

Assume, we have duration source value of 297,44 seconds.
Let's say we have it under the name "/Video/Duration".

Now, we just need to add the letter "P" (to indicate a duration), and "T" to indicate that it's time - and then "S" at the end, for seconds: It might not look as beautiful as formatted as hours, minutes, seconds - but it's actually easier to read back, parse and convert it to whatever output format you need.
