HELP: unknown sub out-of-sync...

[dhruba.bandopadhyay]

I got this really old film called Cyborg 2 in French. I downloaded the English subtitles from:

http://www.opensubtitles.org/subtitles/158914

however I think the subtitles start 2 seconds early. The subtitles file is in a format that I am not familiar with, eg.

{217}{282}<i>In the year 2074,</i>
{290}{332}<i>planet earth is caught</i>|<i>in the grip</i>
{337}{395}<i>of high-powered</i>|<i>corporate warfare.</i>

and the file extension was just plain .txt

Does anyone know exactly what type of subtitle format this file is in, and what editor I can use to increment the time by 2 seconds?
