//program: File Server

/*

Write an HTTP server that serves JSON data when it receives a GET request to the path '/api/parsetime'. Expect the request to contain a query string with a key 'iso' and an ISO-format time as the value.

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.
