    * Subclass from Clock a RouterClock which can access router transports,
      with the goal of developing it to second-guess NTP results
    * Make transports report clock skew in seconds
    * Adjust renderStatusHTML() methods accordingly
    * Show average for NTCP clock skews too
    * Give transports a getClockSkews() method to report clock skews
    * Give transport manager a getClockSkews() method to aggregate results
    * Give comm system facade a getMedianPeerClockSkew() method which RouterClock calls
      (to observe results, add "net.i2p.router.transport.CommSystemFacadeImpl=WARN" to
logging)
    * Extra explicitness in NTCP classes to denote unit of time.
    * Fix some places in NTCPConnection where milliseconds and seconds were confused
