Subttle Synchronization

Write a C or C++ program that takes a subtitle fle(a file with .srt extension) and a signed number (in milliseconds) as its inputs and add/subtract that amount of time from all of the content of the file and store the modified file. For example, consider the following small part of a subtitle from the big bang theory:

1

00:00:03,258 --> 00:00:05,078

Ooh, it's freezing

out here.

2

00:00:05,587 --> 00:00:07,877

Would you like me to...

heat things up?

3

00:00:07,963 --> 00:00:11,056

No, I want to get in the hot tub

before I lose a toe.

4

00:00:12,306 --> 00:00:14,351

Oh. That is bright!

5

00:00:14,436 --> 00:00:16,915

Yeah, a new neighbor

put in floodlights.

6

00:00:17,001 --> 00:00:18,251

Huh.

7

00:00:18,373 --> 00:00:19,798

So, shall we?

8

00:00:20,790 --> 00:00:24,183

No. I don't want to take my

robe off under a spotlight.

9

00:00:24,376 --> 00:00:26,329

This is a candle body.

The first text will appear at 00:00:03,258 till 00:00:05,078. it is very annoying if it is not synced with the movie. Your code moves all of the time forward or backward according to the number of milliseconds that the user specified.
