Latitude does not affect time, it just affects daylight length. Longitude affects time
Now ... the earth is a circle, (360 degrees) it turns once a day, 360 degrees in 24 hours, 15 degrees an hour. The 0 meridian is at Greenwich in London. so 10 degrees east is 40 minutes in front of Greenwich, and 70 degrees west is 280 minutes behind Greenwich. Using this we can say that 70 degrees west is 320 minutes behind 10 degrees east that is 5hrs and 20 minutes take that away from the flight time and you have 4 hours and 40 minutes, this means it will be 06.40 a.m. , local time, when you land

Earth sphear is assumed to have 360 latitude lines, Earth revolution take 24 hrs, thus each degree is considerd 4 Min. time.
Thus every one degree of change in latitude, there will be 4 minute time difference.
It is practicaly not possible to have many time zones, so time zones are divided on 30 minute intervals(7.5 Degree)
All countries select time zone which pass near or center to that country, thus they have one single time even thou local time at each location will be different. try, but for very large country like USA, they have more Time zone for different states.
To calculate locate time difference, get the difference in latitude and multiply by 4 minute, If you are going to east direction then add the time differece with local time, and deduct the same if you are going toward west side.

Well, you start off 10 degrees east of Greewitch Mean Time, and ends 70 degrees west of GMT. Each degree equals to 6 minutes, so 10 degrees means GMT + 1 hour, so suppose your time is 12pm, and thus GMt is 11am. 10 hours later, your time is 10pm, and GMT is now at 9pm. Using same formula, 70 W is 7 hours behind GMT, so 9pm take away 7 hours is 2 pm.

Ok,
local time:
-- departure: 02.00 (day 1)
-- arrival: 12.00 (day 1)
the time difference between the two zones is 5 hours. (download and install Google Earth (http://earth.google.com/ ) and turn on Lon/Lat Grid (Ctrl+L))
so:
destination time:
-- departure: 21.00 (day 0)
-- arrival: 7.00 (day 1)
