My minute and second clock timer works but the second counter display is wrong?

I got this code a while ago and it works perfectly but the display looks odd and got a few complaints.

This is how it counts to 10:

0:1 0:2 0:3 0:4 0:5 0:6 0:7 0:8 0:9 0:10 then 0:11 0:12 0:13

I need it to be:

0:01 0:02 0:03 0:04 0:05 0:06 0:07 0:08 0:09 0:10 then 0:11 0:12 0:13

It works but it looks odd then players pick up on it so it would be nice if i can change it.

The Code is:

System: Every tick: System: Add dt to Timer

Text : Set text : "Time "

Text : Append Text : floor(timer / 60 % 60) & ":" & floor(timer % 60)

I copied the code so dont know if it can be changed to add a 0 before the 1-9 count.

zeropad(floor(timer/60 % 60),2) & ":" & zeropad(floor(timer% 60),2)

Thanks it works fine.
