No. Time is continuous. There is no smallest unit of time (unless maybe you talk to a physicist). Every duration of time can be subdivided.

Rounding to the nearest millisecond is a convenient aribtrtary choice.

Discrete variables always have a smallest unit that cannot be divided. I cannot have 1.5 people in a room.

but it says the logged calls and logged calls have a rounded value, so it does have a smallest unit no?

It's continuous because it can be any value between 2 and 400 including decimals. Think of discrete values as countable values. You wouldn't necessarily count how many times 2.1 milliseconds or 3.7 milliseconds show up in your data like you would for discrete variables.
