Setting the timebase to MS or S works fine, setting to any NS value crashes. It's unclear why this happens, needs investigation.
Problem is one 0 to short on the ns case at line 702 was: case 100000000: must be: case 1000000000: When changed it is working
Are there two issues? A missing 0 which made the setting not take effect. And a missing 'default' case which had prevented the crash?
Fixed in 80eba3857a61931793054f95e6b8c7eac8e3a7fe, thanks!
