The best time is yesterday. The second best is today. The worst is tomorrow..

Well, tomorrow is better than never, so hence not the worst.

To reiterate on day, the better quote would be:

"The best time is yesterday. The second best is today. The worst is some day."

Although it's not what you said, I presume you mean that sooner is better.
