Here one more alternative to your fine list of possibilities.

If pi day is 3/14 then the "pi hour" of pi day could be
15.926535 o'clock, which is 15:55:35 (3:55:35 PM).

Not precise enough? To the nanosecond the exact pi
time of pi day is 3/14 15.9265358979323846264 h =
15 h + 55 m + 35 s + 292 ms + 325 us + 565 ns.
