Load Buddha defiantly do talk about Past, Present and Future. I guess your questions is mainly about, "Do we have something called time?" or "What is time". With regards to Abidhamma, there is no "Paramartha" dhamma which we can relate to time. i.e. There is Chiththa, Chithasika and Rupa and Nirvana, but no reference to time. One of the best explanation I've heard is that the impermanency (Anithya) that we see is what we comprehend as time. i.e. The change that we see, we associate it with time. Sorry if it's not vey helpful.
