* Program name : Time interval *
* Program ver. : 1.0 *
* Created by : SharpDevelop *
* Code author : Perić Željko *
* Code language : C# *
* Date created : 12.12.2013 *
* Time created : 17:31 *
* *
* *
* Program Description : Program for calculating time distance between two dates. *
* *
* *
* Program Accuracy Notice : Program calculates distance between two dates by finding *
* how many seconds has passed from start date to the end date, *
* and then recalculates seconds into *
* years , months , days , hours , minutes and seconds. *
* *
* exmpl: *
* start date-time 29.03.1972 08:40:00 *
* end date-time 12.12.2013 17:34:58 *
* *
* result *
* 41 years *
* 8 monts *
* 14 days *
* 8 hours *
* 54 minutes *
* 58 seconds *
* *
* Minimum date value 01.01.1753 00:00:00 *
* Maximum date value 31.12.9998 00:00:00 *
* *
* All the best, *
* Author. *
