This subroutine may be called to measure the time interval

between events with a specified degree of accuracy. Inter-

vals are stored as non-zero, single precision, unsigned inte-

gers. This is an efficient way to code activity information

since histograms can easily be generated to allow examina-

tion of the activity later.
