New parameter in response "ex"

[a1aw]

I recently found out there is an new parameter in the JSON response in the API.

ex seems represent expire time. Maybe adding in this API to provide scheduled updates/requests to the KMB's API? (in a Thread)

Example of the response:

• Request: (repeated twice/multiple times)

  http://etav2.kmb.hk/?action=geteta&lang=en&route=1A&bound=1&stop=SA06T10000&stop_seq=0
  

• Response 1 from first request: (Remaining 1 min)

   {
      "response":[
         {
            "ei":"Y",
            "eot":"T",
            "t":"23:10?? Scheduled",
            "w":"Y",
            "ex":"2017-01-21 23:20:00"
         },
         {
            "ei":"Y",
            "eot":"T",
            "t":"23:20?? Scheduled",
            "w":"Y",
            "ex":"2017-01-21 23:30:00"
         },
         {
            "ei":"Y",
            "eot":"T",
            "t":"23:30?? Scheduled",
            "w":"Y",
            "ex":"2017-01-21 23:40:00"
         }
      ],
      "updated":1485010839861,
      "generated":1485011437419,
      "responsecode":0
   }

• Response 2: (Arrived/Already left)

{
   "response":[
      {
         "ei":"Y",
         "eot":"T",
         "t":"23:20?? Scheduled",
         "w":"Y",
         "ex":"2017-01-21 23:30:00"
      },
      {
         "ei":"Y",
         "eot":"T",
         "t":"23:30?? Scheduled",
         "w":"Y",
         "ex":"2017-01-21 23:40:00"
      },
      {

         "eot":"T",
         "t":"23:40?? Last Bus",
         "w":"Y",
