Timer interpretation - stata

Question

If i run Stata's timer:
timer on 1
(code lines)
timer off 1
timer list 1
I cannot read the result:
timer list 1
1: 325.15 / 2 = 162.5725
The next time the timer produces:
timer list 1
1: 622.47 / 3 = 207.4883
It seems it is dividing 325.15 by 2, dividing 622.47 by 3.
Why? What does pre-division number mean? What does post-division number mean?
I tried reading the manual on the topic and other information online but I couldn't find any answer.

Answer 1

The first number is the time elapsed in seconds and the second is the number of times the timer was turned on and off.
Using the example from the help file:
program tester
version 13
forvalues repeat=1(1)100 {
timer on 1
quietly summarize price
timer off 1
}
timer list 1
return list
end
And the toy dataset auto.dta:
sysuse auto, clear
timer clear 1
tester
1: 0.01 / 100 = 0.0001
scalars:
r(N) = 74
r(sum_w) = 74
r(mean) = 6165.256756756757
r(Var) = 8699525.974268788
r(sd) = 2949.495884768919
r(min) = 3291
r(max) = 15906
r(sum) = 456229
r(t1) = .008
r(nt1) = 100
tester
1: 0.02 / 200 = 0.0001
scalars:
r(N) = 74
r(sum_w) = 74
r(mean) = 6165.256756756757
r(Var) = 8699525.974268788
r(sd) = 2949.495884768919
r(min) = 3291
r(max) = 15906
r(sum) = 456229
r(t1) = .017
r(nt1) = 200
If you clear the timer again:
timer clear 1
tester
1: 0.01 / 100 = 0.0001

r(N) = 74
r(sum_w) = 74
r(mean) = 6165.256756756757
r(Var) = 8699525.974268788
r(sd) = 2949.495884768919
r(min) = 3291
r(max) = 15906
r(sum) = 456229
r(t1) = .007
r(nt1) = 100
