Driving nervous driver

A man driving a car. Night, he very tired after several hours of driving. At one point, pull over for much needed nap. Never doze grabs it, that it awakens one:
- Excuse me, you have a watch? Angry man responds:
- It's 4:30! It sticks and sleep.
After some time, another his rapping window:
- Excuse me, you have a watch? This and more nervous:
- E 5 not 10! Then write on a large piece "I know what time" and stick to the car.
A third stops and beat them in the window.
- What do you want me? asks the driver pissed.
- It's 5:10!
