Ready when you are
If you want the flexibility to catch any train you want and buy the ticket whenever you want, then Anytime is for you. You can buy ahead, or just walk up on the day, and they're valid on any train on the date shown.
Short answer: any time, any train. But not any date.
Long answer: every ticket has a start date on it.
