Timezone to config

[jonyrock]

in csv file you might get something like

Date Of Stop, ....
09/24/2013 17:11:00, ....

and I have no clue in which timezone is it.

I would add

"timestamp": {
  "name": "Date Of Stop",
  "timezone": "UTC-5",
   ...
}

The thing is that if we have timezine in our csv file value, that we should show error.
For example, 2010-01-01 04:01:01GMT-04:00 already has timezone
