> Unix time is not the number of seconds since epoch

I assumed that is (part of) why he ended up wanting to build his own. The way UNIX time handles leap seconds was arguably a mistake, GPS (and Galileo) time does it right; have the leap second information in a separate field. So as a time scale I imagine OPs one would be similar to GPS but with different epoch. Of course everyone loves having informally defined ad-hoc timescales around
