True.  Agreed.

Unfortunately, so it seems.  Pity that we have to combat "enemies within" our own 
ranks when it comes to continuing progress of the SI system.  Without wanting to be 
"an ultimate Judge" on this, I still think that it's just plain wrong to avoid "facing 
the music" just because of the potential huge implications that further changes could 
bring to the picture.  If, fundamentally, there IS something wrong with the current 
time framework then change we MUST.

BTW, I'm seriously considering contacting a major watch manufacturer and request that 
they build a custom-ordered watch for me.  I'll ask that they build a digital model 
for me with 100 hours of 1000 new seconds of 0.864 of the current one.  Perhaps the 
Swatch company may be willing to do this since they've been heavily involved with 
innovative ideas like the beat thing...

One of the difficulties of decimalization of time is indeed evidently things like the 
above.  However, who said that such shifts would *have to* be equal?...  Since working 
at night is usually more stressful it may stand to reason that we divide it like 34, 
34, 32, for instance (with 4 hours for "lunch")...
