tzconfig

Configure timezone

$ tzconfig

tzconfig [options]

tzconfig is an interactive Debian utility for configuring the system timezone. It presents a menu-based interface that guides users through selecting a geographic region and city to determine the correct timezone, then updates the system-wide timezone configuration by modifying /etc/localtime.
This tool has been deprecated on systemd-based systems in favor of timedatectl, which provides timezone management along with broader time and date configuration capabilities. On older Debian systems without systemd, dpkg-reconfigure tzdata is the preferred alternative.
