Here is an extension to format the time / duration (millis) in different ways:
→ [HH:mm:ss] → [days + HH:mm:ss], → [HH:mm] → [mm:ss] → [HH:mm:ss:S] → [HH:mm:ss:SS] → [HH:mm:ss:SSS] etc.
This is asked very often and always requires a lot of questions / answers and posts in the forum.
Hence this extension (some of it can also be implemented with the on-board methods):
No, it’s not a problem to get the right values (for hours, min, sec), but it’s about formatting the duration correctly, e.g. in this format: [HH:mm:ss] → 01:00:00.
