Learn to read the time on an analog clock face. Practice on the clock below, then try reading hours, then minutes and when you're confident with those separately, try them combined, in actual analog time.
When ready, choose and press

Practice with the clock below.
Change the value in the black rectangle below to something like:
-(hours:minutes), like 13:02, or just
-(hours), like 16 or just
-(:minutes), like :126.
Don't forget the : sign, it separates hours from minutes.
When you're done typing in the time, press the square button. Read the two kinds of time names (regular and military), then start again, with a different time.
