tzupdate | Tests

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

Features

  • Small, easy to understand codebase
  • Queries multiple geolocation services in parallel and returns the first with a successful result
  • Protects against directory traversal and invalid results when linking /etc/localtime

Installation

cargo install tzupdate

Usage

# tzupdate
Set system timezone to Europe/London.

Internally, this geolocates you, gets the timezone for that geolocation, and then updates the system's local time zone.

You can see what tzupdate would do without actually doing it by passing -p, and specify an alternative IP address by using -i. This is not an exhaustive list of options, see tzupdate --help for that.
