Marcus, Bill & friends:
Sorry, but days, hours and minutes are not part of SI and have never
been intended to be. They do not represent a flaw in SI.
This, misfortune for SI has been the imbedding/mind boggler for an otherwise 'Metricated World'. Yes, the Year (Bessilian Year); the Day (MJD count or as I put it - the down count of day (10x100x100 units) distribution among Indus people); or the Seconds (up and down count of time passage in seconds) were resorted to attempt in completing the SI Metric coherence. TRY *Decimalisation of the HOUR in realtion to Arc-Angle* to see results - that shall lead you to the cause of failure of French Republican calendar.
Debating km/hr or m/s as against miles/hr or ft/s are Okay: How do we go about using 'kilometre in Nautical astronomy'. Le Systeme Internationale d'Unites shall remain INCOMPLETE till *Time & Arc-Angle axis* is resolved - for which I provide the direction.

Thirty days in July, September:
April, June, November, December;
All the rest have thirty-one; accepting February alone:
Which hath but twenty-nine, to be (in) fine;
Till leap year gives the whole week READY:
Is it not time to MODIFY or change to make it perennial, Oh Daddy!

And make the calendar work with Leap Week Rule!

Well... As can be seen by Gavin's "nagging"* post below, it looks like this issue would not go away after all, eh?... ;-)

* - I'm making use of this adjective here not in a derogatory sense, but to illustrate that until some issues are addressed by the SI system developers they will NOT be able to provide us with satisfying answers!

Unfortunately though, m/s would suffer from "application-related" shortcomings, something that apparently can only be reasonably addressed by a unit of the magnitude of km/h (not 'hr', ok, Gavin?...).

Evidently, it goes without saying that had time been "metricated" and we wouldn't have such problem, since we'd use a legitimate prefixed unit of time to satisfy such requirement (example: km/ks, or km/h, where hour is "metric hour").
