Common sense is not precise enough for modern physics.

Anyway, if "true" time cannot be measured, i.e. if 
intervals of it cannot be assigned numerical values by the 
use of some apparatus, it is not a physical quantity. 
Perhaps it is a feeling... like when you get hungry? or 
cold?

I do not know what the above means; it seems to be complete 
nonsense; but anyway, it is not physics. Therefore it is 
off-topic for this group, which is called 
"physics at tuks.nl".
