> The NTP Project conducts Research and Development in NTP, a protocol designed to synchronize the clocks of computers over a network to a common timebase.
Research is put front and centre in their pitch for funding.
This is probably research into protocol for time sync. Which works well for some scenarios, but not yet for others and can improve the reference implementation (I guess; I have no hard knowledge there).
And given that ntp.org runs servers that so many organizations use they should be near the top of the funding queue for any NTP research. My 2c.
