How do I get a countdown timer working correctly even at very low FPS?

I am using DT but still my timer slows down when the FPS does (my app grinds to around 15 fps on low end mobiles).

Even when this slowdown happens I want a countdown time to be displayed correctly, but it just slows down along with the rest of the app.

I am using:

+ System: Every tick

-> System: Set main_timer_in_seconds_current_value to main_timer_in_seconds_current_value-1×dt

Cheers

SOLVED

Apparently below 30fps C3s default behavior is to slow down time. (?)

To fix this I just set the minimum frame rate to 5 fps.

Now the countdown works as expected...even when the FPS is god awful.
