Jquery Autocomplete (API or Database) : Fetch Time zone, Latitude, Longitude and DST of given City Automatically

I have an astrology script that can do some astrological calculations. Besides birth details, my script needs longitude, latitude and time zone of a place/city to do calculations which I have to enter manually. I want a Database or API (Google Places or Geonames Web API) for astrology script to fetch time zone, longitude and latitude of the given place/city automatically. It should also take care of DST (Daylight Savings Time) to do precise and accurate calculations.

My main requirements are as follows:

1- JQuery autocomplete should fetch City name, time zone, longitude and latitude

2- Apart from fetching time zone, longitude and latitude automatically, user should also have an option to enter them manually

3- I will need full source code

4- I should be able to copy-paste your code into other similar astrology scripts.
