Is time discrete or continuous?

I know we largely treat time as continuous, but is there is there a "smallest time unit" that is possible? If so, what ramifications does it have for things like acceleration or movement in general?

Not so far as any experiment to date has been able to detect. There are some models in which the Planck time (about 5.391×10^-44 seconds) is the smallest meaningful amount of time, but they're all entirely speculative at this point.
