And it has been in use by Microsoft in the Excel spreadsheet since
the Apple Plus which didn't have floating point hardware. But then
Excel uses the day as the unit. the second would be better.

No, because the offset is not constant. The delta between TAI and UTC
is currently 34 seconds. Two months ago it was 33 seconds. The next
time there's a leap seco

Considering time scales, there are three that significantly
interrelate, and no matter what Perl 6 uses internally, it needs to be
