Sauf si la nouvelle version de Duration prend garde d'avoir nanos < NanosInSecond Ce qu'elle fait dans certains messages de création mais pas dans tous.
Unless new version of Duration takes care to assert nanos < NanosInSecond Which is done in some instance creation messages but not all...
I guess the reason of the changes were to avoid LargeInteger operations and gain some efficiency. It might not be the best idea to revert to a slow implementation. We should better correct instance creation to always assert nanos < NanosInSecond.

[3500 milliSeconds asDelay wait] durationToRun
donne 0:00:00:00.3501 sur Squeak3.10.2, mais donne le format correct 0:00:00:03.5 sur Squeak3.8.2.
le problème vient de
Duration class>> days: days hours: hours minutes: minutes seconds: seconds nanoSeconds: nanos
^ self seconds: ((days * SecondsInDay) + (hours * SecondsInHour) + (minutes * SecondsInMinute) + seconds) nanoSeconds: nanos
... qui est faux, car les nanoseconds ne participent pas au calcul des seconds.
la version précédente est:
days: days hours: hours minutes: minutes seconds: seconds nanoSeconds: nanos
^ self nanoSeconds: ( ( (days * SecondsInDay) + (hours * SecondsInHour) + (minutes * SecondsInMinute) + seconds ) * NanosInSecond ) + nanos.
et là ça marche.
