Check the sanity of the synchronized clock by comparing its uncorrected frequency with the system monotonic clock. When the measured frequency offset is larger than the value of the sanity_freq_limit option (20% by default), a warning message will be printed and the servo will be reset. Setting the option to zero disables the check. This is useful to detect when the clock is broken or adjusted by another program. Signed-off-by: Miroslav Lichvar <mlichvar@redhat.com>
