Hello Maurice Kinal!

But what if two or more systems process messages at exactly the  
same time of the day?  A collision seems far more likely than if  
the respective systems produce random 32 bit strings.

Right. Therefore, I see two +1's for the random [a-z]|[A-Z]|[0- 
9] version, and atleast one -1 for the time-serial version.
