Hello, I found a bug in the c++ bindings of libgpiod that affects 32bit systems. Observation: Only the c++ bindings lib is affected. For input events, the time stamp delivered in the event object is wrong. Instead of providing a complete "system time", it delivers time stamps of of a range "-2.1"...+2.1 seconds (which relates to the time stamp range of a signed 32bit value, in nanoseconds). Cause: The bug is in line 219 of file "/tree/bindings/cxx/line.cpp": event.ts.tv_nsec + (event.ts.tv_sec * 1000000000)); "event.ts.tv_sec" is of type signed long, which is 32 bit on my device. Thus, that multiplication to convert total seconds of a system time to nanoseconds causes an overflow. Fix: There should be a cast to uint64_t before the multiplication. Thank you for fixing this! Regards, Florian
