I hope that someone might consider reading this paper and using the
ideas that it explains in any attempt to provide access to multiple
clocks:
http://www.kokkinizita.net/papers/usingdll.pdf
delay locked loops are a fundamental tool used in systems with
multiple clocks, and they make it possible to always ask the question
"given time T on clock 1, what is the time on clock 2" and get an
extremely accurate answer.
