How 'bout DateTime?
The DateTime#>> operator means "return a new Date object that is n months
later than the current one."

For your code to work db_cert_date would have to be a DateTime, too.

irb(main):018:0> a = DateTime.now
=> #<DateTime: 35342700409548349/14400000000,-1/6,2299161>
irb(main):019:0> puts a.strftime('%m/%d/%Y')
09/10/2007
=> nil
irb(main):020:0> b = a >> 72
=> #<DateTime: 35374265209548349/14400000000,-1/6,2299161>
irb(main):021:0> puts b.strftime('%m/%d/%Y')
09/10/2013
=> nil
