Which command is used to check the current date and time settings in Linux?

The command used to check the current date and time settings in Linux is timedatectl. This command is part of systemd and provides a comprehensive interface for querying and changing the system clock and its settings. It not only displays the current date and time but also provides information about the time zone and whether system time is synchronized with a network time protocol (NTP) server. Additionally, it lets users adjust the time zone and enables or disables NTP synchronization.

While the date command also shows the current date and time, it lacks the features and details that timedatectl provides, such as time zone information and NTP settings. The ntpdate command is used to set the system's clock from a specified NTP server, rather than just checking current time settings. The clock command is a legacy way of managing the system clock, but it is less common and typically not as informative as timedatectl in modern Linux distributions. Therefore, timedatectl is the most appropriate command for checking date and time settings comprehensively.
