Comment (by Balling):

 On latest:

 [blackdetect @ 00000292367c4040] black_start:22.089 black_end:'''23.49'''
 black_duration:1.401
 [blackdetect @ 00000292367c4040] black_start:46.046 black_end:48.549
 black_duration:2.503

 Looks like it truncates zeroes.

 Also with mp4:

 [blackdetect @ 000001fd2252d4c0] black_start:0 black_end:1.08442
 black_duration:1.08442

 but with mkv:

 [blackdetect @ 000001917179b840] black_start:0 black_end:1.001
 black_duration:1.001

 I can confirm the issue on latest git master.
