  2 * tstotv - tables for converting from NTP time stamps to struct timeval

  8 * Tables to convert from a time stamp fraction to usecs.  Note that
  9 * the units of these tables are actually (usec<<3).  We carry three
 10 * guard bits so that the result can be properly truncated (or rounded)
 11 * to be correct to the least significant bit.
 12 *
 13 * These tables are rounded.
