Error when shifting files

[tjavier82]

I have this subs:

1
00:00:00,058 --> 00:00:02,942
Previously on AMC's
Breaking Bad...

2
00:00:02,984 --> 00:00:04,513
Sooner or later
someone is gonna flip.

If I shift this subs -1 seconds, the resulting file has all this subs at 00:00:00,000

1
00:00:00,000 --> 00:00:00,000
Previously on AMC's
Breaking Bad...

2
00:00:00,000 --> 00:00:00,000
Sooner or later
someone is gonna flip.

3
00:00:00,000 --> 00:00:00,000
I've got nine guys.
They were part of the

I think it should be 00:00:00,000 at first and then -1 second.

I'm sorry but I'm not able to reproduce. Can you show me a code sample that behave like that please ?

from pysrt import SubRipFile
subs = SubRipFile.open ('Breaking_Bad_-5x08-_TBA.HDTV.asap.en.srt')
subs.shift(-1)
subs.save('out.srt',encoding='utf-8')
exit()

$ head out.srt

Ok it's a bit difficult to see but the shift method signature is:

 shift(hours=0, minutes=0, seconds=0, milliseconds=0)

So you ask to shift 1 hour back.
Try this

subs.shift(seconds=-1)

You're welcome. It's my bad, I've never took the time to write a proper documentation.
