1958 Science 18 July 158/3 Intervals in the nanosecond (10⁻⁹) range are said to be measurable.

1959 W. C. G. Ortel in IRE Trans. Electronic Computers 8 265 (heading) Nanosecond logic by amplitude modulation at X band. [Note] Although the term millimicrosecond has attained some currency, the metric system provides the standard prefix nano-, (abbreviated n-), by which the decimal multiplier 10⁻⁹ may be denoted conveniently without multiple prefixes.

1967 New Statesman 14 July 47/3 It takes a nanosecond for an electric signal to travel a foot.

1972 Sci. Amer. Jan. 121/1 Present atomic clocks keep time to better than 100 nanoseconds per day.

1982 Giant Bk. Electronics Projects iii. 126 Any logic transition which lasts at least 50 nanoseconds is detected.

2000 Nature 27 Apr. 919/9 IBM has achieved affordable MRAMs of about 1 kilobit capacity with access times of less than 3 nanoseconds.

2. hyperbolically. An extremely short period of time.

1983 Judge Dredd Ann. 1984 28/2 Not a nano-second too soon.

1998 Chicago Tribune 23 Mar. i. 12/1 Money pours into emerging markets, then flees in nanoseconds for better returns elsewhere.

2000 New Republic 3 Apr. 14/2 I've seen governors come and go..and this one's attention span can be measured in nanoseconds.
