Q: If you have one missing Announce per second, when will it overflow?

A: 2^64 = 18446744073709551616 s
        = 5124095576030431 h
        = 213503982334601 d
        = 584542046090.6 y
        = 5845420460.9 c

(but I neglected the possible future leap seconds ;^)

So it never overflows, practically speaking.

Applications can simply latch the current value and subtract it from
subsequent reads in order to "reset" the counter.

Thanks,
Richard
