Provides a simple command-line interface for natural language time zone conversions. Performs queries like "right now in london and paris", "2pm in berlin", "9am for me in Rome", and optimized queries relative to your local time zone like "best time to reach tokyo".  If your other Slack mates are also using it, you can query with their @username as well, e.g. "best time to have a meeting with @joe".  Once installed, just type in "/tz help" to see all of the options.
