In general I think it's best to just refer to POSIX on this matter, and not try to restate the definition. POSIX is very clear and explicit about the day-based accounting of seconds. http://pubs.opengroup.org/onlinepubs/9699919799.2016edition/basedefs/V1_chap04.html#tag_04_16 > However, there may be C-DNS purposes that cannot tolerate such > discontinuities, and they would presumably want to use a continuous monotonic > timescale with a fixed offset from TAI (as is the case for e.g. GPS time). That's practically unobtanium on most systems :-) Even if you have PTP there isn't a fixed PTP epoch, though the SMPTE profile defines it to be equivalent to POSIX time plus the TAI-UTC value from the IERS / NIST leapsecond tables.
