You can use intervals to do this. Intervals can specify a time difference
in years and months as well as days, hours, seconds, etc. The documentation
doesn't indicate which part is added first. A quick check indicates
that month, year gets added before day, hours, minutes, seconds, but
you might want to double check the code before relying on this.
