The PPS assert/clear offset corrections are set by the PPS_SETPARAMS ioctl in the pps_ktime structs, which also contain flags. The flags are not initialized by applications (using the timepps.h header) and they are not used by the kernel for anything except returning them back in the PPS_GETPARAMS ioctl. Set the flags to zero to make it clear they are unused and avoid leaking uninitialized data of the PPS_SETPARAMS caller to other applications that have a read access to the PPS device.
