- If using the Linux RT Base System Image:
- cat /var/lib/ni-timesync/tsm.json | grep "phc2sysEnable"
- If using Legacy Installation:
- cat /usr/local/natinst/share/TimeSync/tsm.json | grep "phc2sysEnable"
If you are unsure which software installation method you are using, you can run both command and determine your software installation method and status of Linux OS time synchronization based on its output.
Below are the response and its definition that you can get after execute each of the command:
- "phc2sysEnable": true
- Linux OS time synchronization is enabled
- "phc2sysEnable": false
