positive.code: = Timezone Queue Rollover (Enterprise Edition Feature)
  
  In Chronicle Queue the time queues are rolled over is based on the UTC time; it uses `System.currentTimeMillis()`.
  
  The Timezone rollover Enterprise feature extends Chronicle Queue's ability to specify the time and periodicity of queue rollovers, to take account of the user's location timezone rather than UTC.
  
  NOTE: This feature is only relevant to daily rollovers (`RollCycle` is one of `SMALL_DAILY`, `DAILY`, `LARGE_DAILY`, `XLARGE_DAILY`, or `HUGE_DAILY`).
