14 * Tables to calculate time stamp fractions from usecs.  The entries
15 * in these tables are offset into using each of the two low order
16 * bytes plus the next 4 bits in a usec value (from a struct timeval).
17 * These are summed to produce the time stamp fraction.
18 *
19 * Note that these tables are rounded (not truncated) to the nearest
20 * low order bit in the fraction.  The timestamp computed should be
21 * +- 1.5 low order bits.
