Describe the bug
When I set the "Shutter Fire Interval" to 1 minute and then use "Interval Mode", the delay between the pictures is 61 seconds, not 60 seconds.
Expected behavior
I am not expecting particularly accurate timing. I am expecting the cumulative delay to not exceed 1 minute. (The cumulative delay in my example has reached 20 seconds after 20 photographs - by extrapolation, the cumulative delay will exceed 1 minute after 60 photographs.)

I have not had the time to see how FreeDcam schedules its intervals, but I have found that https://github.com/floe/Background-Timelapse uses scheduleAtFixedRate.
HTH.
