Keywordtest - Convert to Int and then increment

Hi,

I'm using keyword test; I need some help here:

I have a string. for example, 14:20, I have captured it successfully.

But i need to convert this to integer and the have to increment the last digit to 1 (i.e, 14:20).

I believe we need to add code snippets but can someone share some examples such as how to convert str to int and how to increment them?

REgards,
