Obligation: I should be going now. It's getting late.

Most modal verbs have different forms depending on their function when used in the present, past or future times.
Here are some examples:

Present: You should do more exercise. / You shouldn't smoke.
Past: You should have done more exercise. / You shouldn't have started smoking.

For obligation 'be supposed to' can replace 'should'.
