Close. They are 100 ns granularity cluncks with a signed 64 bit
counter since the Smithsonian base date 00:00 17-Nov-1858.

So it will happily represent the date of birth for a centenarian, as
well as the end date for a new 99 year lease.

The build-in ascii formatting is restricted to the year 9999 and
typically includes centi-seconds.

The negative times are considered 'delta times', which are formate to
DDDD HH:MM:SS.CC

fwiw,
Hein.
