  14.  * Known bugs:                                                               *
  15.  *   - Since the counter is a 32-bit millisecond counter, it will wrap after *
  16.  *     4.2 billion milliseconds. It will take a couple of weeks for the      *
  17.  *     counter to wrap.                                                      *
