on February 25, 1991 American Patriot Missile battery in Dhara failed to track incoming missile because they used floating point time instead of integers. 28 dead 100 injured time precision was decreasing with time since system was booted and after about 100h of operation this accumulated enough to system believe that incoming missile is already unreachable using existing calculations and caused it to not react at all I think that is great example why changing precision depending on time might be very bad idea. imagine that afer Y2038 that slight drop in precision would cause some critical system to fail in unexpected way
