Impossible to define 24h time range

[marcelstoer]

Take the sample in this repository and try to define a 24h time range. What should the values for startTime and endTime be?

The closest I got was with using startTime: "01:00" and endTime: "00:00" but of course I'm missing 1h.

If you define startTime: "00:00" and endTime: "00:00" the <div> remains empty although no error or the like is reported on the console. The same goes for 00:00 - 23:59.
