Time Difference Calculator

This applicattion provides the possibility to calculate the difference between to time periods.
This app were built for my personal usage, but decided to share with you my friend.
This application is very usefull when you have a train in the evening and need to set a timer on your watch, it just simplifies the calculation, because during the rushing and travelling your brain may get stuck and you may calculate the time difference incorrectly. Or during the flight and train, you can set timer on your watch and monitor the time left till the end of the trip, by just using this application by calculating the start and finish trip time.
