The RM says that "Time" is supposed to be able to represent a value,
from program start, of at least 50 years. So if a 10-second program
is overflowing that time, you've got a problem.
I tried a program similar to the above on two different compilers,
with "delay 10.0" in the place where you have "I run my algorithm
here"; and in both cases the output is around 10.0. I don't know why
you'd be seeing zero, assuming the system you're on has a working
clock. What type of machine are you running on, and what compiler?
