There is a user-written Stata command called -diff- that performs
difference-in-difference analysis.  But as this short set of slides shows,
it gives results that are equivalent to the t-test for the Time x Treated
product term in a regression model.

If you are presenting to an audience that expects the results presented as a
Difference-in-Differences analysis, you could just tailor your results
accordingly.  (And show any skeptics those slides by Oscar Torres-Reyna.)
