* the timestamp can be off by a range of 0 to 429.4967295 seconds (or 7
* minutes, 9 seconds, and 496730 microseconds).
*
* 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
