ntpq -p

Active Sync Time Source

1. Look for the asterisk * in the first column, which identifies your currently selected active time source.
2. The reach column should ideally be 377 (octal), confirming the server has been successfully contacted over the last 8 polls.
3. The offset should be a very low number (typically under 100 milliseconds), showing how far off your clock is from the server.
