Hi, I writed a code to show a real time indicator for "time spent in the lesson", but i don't know how to implement this on official moodle repository, i have edited "mod/lesson/view.php" and "mod/lesson/lang/en/lesson.php" file.

Can anyone explain me how to post my code?

Thank You!!!

I didn't find the right solution from the Internet.
