Today's emphasis is on extreme accuracy in minute units of time. Our modern world depends upon split second coordination, upon the precise definition of When? and How long? An international conference in 1956 established a new length for one second of time defining it as a fraction of the length of the year. The second had previously been defined as 1/86,400 of a mean solar day. Still earlier 1/86,400 of any solar day was precise enough. - Information Supplied By: Herbert W Armstrong Library
