ntpq (NTP query program)

ntpq is a command-line tool used to communicate with Network Time Protocol (NTP) servers, which synchronize computer clocks across the internet. It helps users check the status, accuracy, and health of NTP servers, ensuring that time is consistent and reliable. By sending queries, ntpq provides information about server responses, time offsets, and synchronization status, allowing administrators to verify proper time alignment, troubleshoot issues, and maintain accurate system clocks crucial for security, logging, and coordinated operations.
