This note is in response to Bill English's Request for Comments:  28.
 
A "millisecond" clock should be satisfactory for most network measurements.
Round-trip message transit times typically should be at least on the
order of tens to hundreds of milliseconds.  The IMP contains a 16-bit
hardware clock which is incremented every 100 microseconds to allow for
timing of internal events within the IMP, as for example, during tracing.
However, most measurements are made using a 25.6 ms. software clock.
