If Snape had been teaching 14 years in the fall of 1995, then he
started in the fall of 1981.  The Potters were killed in the fall of
1981.  We don't know exactly when the Potters were first targeted by
Voldemort, but it couldn't have been before Harry was born--in July
'80.  Where do you get the two years? I think the confusion comes from
people assuming that Snape only approached Dumbledore once. There is
no evidence in text for that assumption and it makes no sense.

At the same time (fall '95) that Snape has been teaching 14 years,
Trelawney says she has been there 16 years.  1995 - 16 = 1979.  If she
is being accurate, then the prophecy was made as much as a year before
Harry was born.  One the other hand, the label on the sphere when the
DAs see it (June, 1996) gives a date "of some sixteen years" earlier
(1980). Maybe Trelawney had had a little too much sherry.  But either
way, the prophecy was made somewhere between a few months and a year
before Harry was born.
