I don't know Multisim 11 but:
There is a "scope probe" where you can look at the wave form. The output of the LM555 is like this:
-------____-------------------______------------------______----------
If the hour is counting at all then the LM555 must be working.
For each block (Hour, Minutes, Seconds) they should count. The QA,QB,QC,QD should start out 0,1,2,3,4.......end count,0,1,2,3......
I know there are many ways of looking at points in your project.
QA----____----____----____
QB_______----------______
QC_____________----------
or
QA:QB: 0 1 2 3 4 5 6
