[Glass] Time and System millisecondsToRun

[bruno buzzi brassesco]

Hi,

Why there is a difference answer in the following expressions ? (tested 
on GS 3.5.1 and 3.3.7)

Time millisecondsToRun: [(Delay forSeconds: 4) wait]. "answer 4000  -> 
computing the delay time "

System millisecondsToRun: [(Delay forSeconds: 4) wait]. "answer 0 -> NOT 
computing the delay time"

It seems a difference in how time is computed:
System use primitive 178 and Time use primitive 13.

So Time check actual time difference while System check CPU time 
consumed then excluding delays.

regards,
bruno
