Now will move forward how to parse the same in the easiest way.

Did somebody mention State Machines...?

Quote:

One common method is to convert time to seconds add/subtract your offset then convert back to 'real' time. Its a common problem.

Does your compiler offer functions like localtime() and mktime() ?
