Working with dates in axapta

when you are working with dates in axapta the following samples may useful for you.

systemdateget() + 10;   //Add 10days to a date
dateMthFwd(systemdateget(), 5);   //Add 5 months to a date
dateMthFwd(systemdateget(), 36);   //Add 3 years to a date

here dateMthFwd is the system function it will converrt the months into years.but we dont have function to add the number of years directly to that function.
