Derive time of conception or birth from DNA analysis?

Are there any studies, past or present, devoted to the idea of deriving precise time of either conception or birth from DNA analysis? For conception, I can imagine a science fiction author describing a rhythmic pattern or pulse emitted by something in the DNA whose beats are somehow recorded somewhere, like the veritable second hand of a clock. For birth time I'm a little fuzzier on the possibilities, but one idea that occurred to me was the studying the effects of direct light (sun or artificial) on a baby's chromosomes when exposed for the first time (not counting any rays that might penetrate the womb through the mother). There is also the telomere clock to consider, about which I know very little.
