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.
