[Feature Request] Seconds to timestamp (HH:MM:SS)

Could it be possible to add a new command to web script to convert a number of seconds to a time stamp?

Just imagine we have selected a json value "292", using a command like convert it to "00:04:52"

Now it is hard to get the value using replace and regexpreplace

Just wanted to give a short update here. The next version will have a SayDuration function which emits a formatted duration string.

Edit: This is now available with Mp3tag v3.21b.
