hardpps() produced offset component. This is tested and behaved stable with frequency offsets from -338.05 to +499.91 PPM. Interestingly the machine I tested this on would fail if the clock were slower than 14.3132 MHz whereas it was perfectly happy to run at 16.384 MHz, in other words [-340PPM ... +14.4%] Make pps_shift tweakable with sysctl. |
