NTP
ntpcheck
CLI and library to perform various NTP-related tasks, including:
- replacement for
ntptimeandntpdatecommands - human-readable diagnostics for typical problems with NTP based on data from chrony/ntpd
- server stats and peer stats taken from chrony/ntpd with output in JSON
Quick Installation
go install github.com/facebook/time/cmd/ntpcheck@latest
NTPResponder
Simple NTP server implementation with kernel timestamps support
PTP
pshark
Simple tool to read pcap/pcapng captures and parse and print PTP packets from there. Allows to test our protocol parser implementation against arbitrary tcpdump capture. Also the code shows integration with GoPacket library.
ziffy
CLI tool to triangulate datacenter switches that are not operating correctly as PTP Transparent Clocks.
ptpcheck
CLI and library to perform various PTP-related tasks, including:
- reporting stats taken from local PTP instance in JSON format
- running basic unicast client to showcase or debug PTP protocol internals
- running human-readable diagnostics for basic problems with PTP based on data from local PTP client (ptp4l).
- comparing system time with PHC time
- mapping PHC devices to network cards and vice versa
- sync 2 PHCs
Quick Installation
go install github.com/facebook/time/cmd/ptpcheck@latest
ptp4u
Scalable unicast PTP server.
Quick Installation
go install github.com/facebook/time/cmd/ptp4u@latest
sptp
Scalable unicast SPTP client.
Quick Installation
go install github.com/facebook/time/cmd/sptp@latest
c4u
Config generator for ptp4u.
Quick Installation
go install github.com/facebook/time/cmd/c4u@latest
fbclock
fbclock-daemon
Stateful part of fbclock (TrueTime service).
Quick Installation
go install github.com/facebook/time/cmd/fbclock-daemon@latest
fbclock-bin
Simple binary written in C that uses client part of fbclock service.
Quick Installation
cd cmd/fbclock-bin
make
Calnex
Command line tool for a Calnex Sentinel device Cli Supports several basic commands such as:
- Firmware upgrade
- Configuration of the device
- Measurement data export
- Device reboot
- Device clear
- Device problem report export
Quick Installation
go install github.com/facebook/time/cmd/calnex@latest

checker
Package checker provides an easy way to talk to NTPD/Chronyd and get NTPCheckResult, which abstracts away Chrony/NTP control protocol implementation details and contains tons of information useful for NTP monitoring, like NTP server variables including offset, peers and their variables and statuses.
