tzupdate is a fully automated utility to set the system time using geolocation.

By default, tzupdate will geolocate you, get the timezone for that geolocation, and then attempt to link that timezone to /etc/localtime. You can pass -p to print the detected timezone without linking. You can also pass -a to pass an IP address to use, instead of geolocating you.

$ sudo tzupdate
Detected timezone is Europe/Dublin.
Linked /etc/localtime to /usr/share/zoneinfo/Europe/Dublin.
