     * local identifier. When constructing the timestamp value for date
     * purposes, we replace the local identifier bits with zeros. As a result,

     * Astute observers might note this value directly corresponds to 2^32 - 1,
     * or 0xffffffff. The local identifier is 32-bits, and we have set each of
     * these bits to 0, so the maximum range of timestamp drift is 0x00000000
     * to 0xffffffff (counted in 100-nanosecond intervals).
