It seems to me like SRT format, but I am not sure.
I don't think it is in SubRip (i.e., .srt) format.
In SubRip, the text starts on the beginning of lines:
00:00:20,000 --> 00:00:24,400
Altocumulus clouds occur between six thousand
00:00:24,600 --> 00:00:27,800
and twenty thousand feet above ground level.
