Pool Fill: SNTP Client

Thought through this some more today. I considered several approaches and settled on the approach of making local time a display artifact. All internal time will be in UTC (same as NTP servers) and adjusted for the user when viewing the time. This has a couple of implications for the pool fill controller:

  1. controller needs to be told the current local time shift (including DST)
  2. controller needs to shift all interactions with the user
  3. does the controller store set points in localtime or UTC?
