Here's how longitude converts into your personal time zone: 15 degrees of longitude = 1 hour difference; 1 degree longitude = 4 minutes difference. 15 minutes of longitude = 1 minute difference; 1 minute of longitude = 4 seconds difference.
Time zones are another arbitrary societal choice, like the origin point of the Prime Meridian. They are based on longitude and defined by Earth's rotation, which completes a full circle (360 degrees) each day (24 hours). Each hour then, Earth rotates through 360/24 = 15° of longitude: the width of one time zone.
Each degree is further divided into 60 minutes ( ' ) and each minute into 60 seconds ( “ ). The latitude of a place on the earth's surface is its distance north or south of the equator, measured along the meridian of that place as an angle from the centre of the earth.
To find the time zone in hours of a particular location, you can take the longitude -- in degrees -- and divide it by 15. So, for example, 75° E would be 75/15 which equals 5. That translates to the time zone being 5 hours ahead of UTC or GMT time, which can also be labeled as UTC+5.
you can calculate the time zone yourself for more help refer this answer may be this can help you....
EDIT: you can use the weatherbug api to get the exact time using your lat/long

I just came around with similar project recently. I now using the web service provided by GeoNames and TimeZoneDB.
Both service need to register a API key.
GeoNames: api.geonames.org/findNearbyPlaceName?lat=47.3&lng=9&username=demo&style=full
TimeZoneDB: api.timezonedb.com/?lat=53.7833&lng=-1.75&key=KEY

Your question may same like

You can use webservice, http://www.earthtools.org/webservices.htm#timezone ,
