marker.end takes seconds not time object

[raeulein]

To set the end of a marker you have to provide seconds as a number but the output of marker.end is a Time object.

So it would be right to set:

marker.end = 12.7

But this would fail:

marker.end = marker.end

Instead this is right:

marker.end = marker.end.seconds
