Why are cells formatted as time, returned as a Duration?

I was wondering why a cell formatted as a "time" value (e.g. 22:30:15 using HH:MM:SS) are returned as a Duration rather than a LocalTime?

It's not a big deal to convert that into a LocalTime instance, but I find the choice of Duration a bit surprising.

Not reason, it should be LocalTime. Not sure why I thought Duration was the right class for this.
