/*
HTTP JSON API SERVER
Servidor HTTP para servir dados JSON, quando recebe GET request a '/api/parsetime'
*
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 }
