No, but you can easily slice out what you want -- localtime()[0:3] -- 
or wrap it with a function that does the same -- def localymd():
return localtime[0:3].

The mathematical approach is to convert both ymds to Julian days and
subtract to get number of days of life.  But since 'month' does not
have a fixed number of days, it is hard to convert back to get the
commonly expected answer for (y,m,d)s of life.  So you need to do the
subtraction the way it is commonly performed or at least the way you
want it to be   (The problem is to figure out what to do when you need
to 'borrow' a month in order to subtract days.)
