Worth emphasizing that decimal time is not just historical curiosity and fringe idea, especially the astronomical community uses decimal time fairly regularly, various "julian date" systems attest that. <a href="https://en.wikipedia.org/wiki/Julian_day" rel="nofollow">https://en.wikipedia.org/wiki/Julian_day</a>

Reminds me of Vernor Vinge's future human starfaring civilization using kiloseconds, megaseconds, and gigaseconds to measure time. <<a href="https://neurocline.github.io/dev/2015/08/13/telling-time-in-seconds.html" rel="nofollow">https://neurocline.github.io/dev/2015/08/13/telling-time-in-...</a>>
A while ago there was a HN post about a metic time website, I still look at it sometimes: <a href="https://metric-time.com/" rel="nofollow">https://metric-time.com/</a>

If we didn't have ten fingers would we care so much about decimals? They aren't particularly well suited to anything more than any other number system. Base 12 actually has a lot more going for it.
