#Canrhs timekeeper wsu driver

Per-source and per-server summary of hardware timestamps. The file timekeeper_stamps.log in the configured LOGDIR directory will show a Src|offset |source type |update age(s)|timestamp typeĠ 0.000000072 PTP(10.0.0.12:0,unicast,telcom) 0 TIMESTAMPING_HW Primary source type: PTP(10.0.0.12:0,unicast,telcom) Primary source offset: 0.000000072 seconds Internal timestamps are similar to software timestamps but can be a little noisierīecause they’re taken further up the stack and are subject to more scheduling noise. Internal timestamps, indicated by ‘INTERNAL’.

#Canrhs timekeeper wsu driver

If the driver doesn’t provide either, TimeKeeper falls back to its own If the network card doesn’t provide hardware timestamps (or hardware timestamp data isn’t usable for some reason), the driver/stack can provideĪ software timestamp which is indicated by ‘TIMESTAMPING_SW’. The TIMESTAMPING_HW indicates that hardware timestamps are used. The output should look something like the below when You can verify that once TimeKeeper is running with the tkstatus command. It will enable and verify these features by default if they’re enabled in the operating system. When running on a platform that supports hardware timestamps there is no additional work needed toĬonfigure TimeKeeper to use them. TimeKeeper does not support hardware timestamp features

Supported on Windows too, starting with Windows 11 and Windows Server 2022. Hardware timestamps have been supported with TimeKeeper on Linux for many years, and is now TimeKeeper transparently detects and take advantages of any network card hardware timestamp features when the operating system,ĭrivers and hardware supports them.

TimeKeeper manages the clocks on these devices and steer them to theĬorrect time without any user interaction or configuration. For those timestamps to be useful theĬlock on the network card must have good time. Improve the accuracy of timestamps because there are no software delays in those timestamps. Network cards with hardware timestamp capability have clocks on them that timestamp a packet when it arrives.
