TAI64 looks good (quotes from DJB's definition):

 "TAI stands for Temps Atomique International, the current international
 real time standard."

 "TAI64 represents a few hundred billion years of real time with
 1-second precision."

 "One-second precision is inadequate for many applications. This section
 defines 96-bit and 128-bit formats, TAI64N and TAI64NA, with nanosecond
 and attosecond precision respectively. ..."
