1.1 English

A new option is added to the ptp_utc_valid_handling parameter in the sfptpd configuration file.

The override option sets a fixed UTC offset (seconds) value and sfptpd will ignore the UTC offset value sent by the upstream master clock. The option is provided as a means of protecting clocks against misbehaving PTP master clocks.

See the ptp_utc_valid_handling option in Instance-specific Configuration Options.
