Is there an equivalent of the Planck length for time? I'd just like a term I may use (high-level) for a similar "unit of time"? I am not looking for a debate on how discrete time might be, but if there is a term I can use that complements Planck's constant for space, I'd like that. [This][1] doesn't help at all.
