From Memory Alpha, the free Star Trek reference

Hi, I'm Robert Treat and have been a Trek fan since the 1970's. I have a three-part guide at Amazon that attempts to reconcile a stardate timeline in TOS with equipment upgrades that take place along production order. I've also written a few online mirror universe stories, including A Debt of Honor and The Gift. They're both rather dark stories, but that should probably be expected with the MU.
