a fraction of a second.

an extremely small period of time; instant
made or arrived at in an infinitely short time: a split-second decision
depending upon minute precision: split-second timing
An instant, a fraction of a second, as in Our best swimmer came in a split second before theirs. This expression alludes to a stop watch that has two second hands, one above the other, for timing more than one athlete or intervals of a race by a single athlete. Each hand can be stopped independently of the other, so a second can be “split” when one second hand stops a fraction of a second after the other. [ c. 1880 ]
