time returns the number of (whole) seconds since the start of the unix epoch. Time::HiRes provides a version of time with better resolution.
Note that Time::HiRes::time only gives answers in steps of 2**-22 seconds or 0.24µs. (For a full explanation, see https://stackoverflow.com/a/66487325/5781773)
