/**
For example:

  /api/parsetime?iso=2013-08-10T12:10:15.474Z

The JSON response should contain only 'hour', 'minute' and 'second' properties. For example:

    {
      "hour": 14,
      "minute": 23,
      "second": 15
    }

Add second endpoint for the path '/api/unixtime' which accepts the same query string but returns UNIX epoch time under the property 'unixtime'. For example:

    { "unixtime": 1376136615474 }

Your server should listen on the port provided by the first argument to your program.
