Finding No. of ticks Between Two Dates in C#

In Some cases we need to calculate the No.of ticks between two time or dates.In c# we can use this function to find the no of ticks.
Here i calculate the ticks between 1970,1,Jan

DateTime dt70 = new DateTime( 1970, 1, 1, 0, 0, 0, 0 );
long ticks1970 = dt70.Ticks;

To calculate up to current time

int gmt = (int) ((DateTime.UtcNow.Ticks – ticks1970 ) / 10000000L);

or you can convert back:

int gmt = 0x3e482b89; // sample GMT time in seconds since 1970
DateTime yourDateTime = new DateTime( ticks1970 + gmt * 10000000L );
