Too lazy to switch from the terminal to check the time? Same. smt displays the current time across multiple timezones in a neat table, right where you already are.

gem install smt

Create a ~/.smtrc.yml file with your timezones:

- emoji: "🇵🇱"
  label: Warsaw
  time_zone: Europe/Warsaw
  color: red
- emoji: "🇬🇧"
  label: London
  time_zone: Europe/London
  color: blue
- emoji: "🇺🇸"
  label: New York
  time_zone: America/New_York
  color: green

Labels support strftime format codes, so you can use dynamic values like %A for the day name.

smt                          # show current time
smt -t "2026-02-04 15:00"   # convert a specific time
smt -f "%H:%M"              # custom time format (default: %Y-%m-%d %H:%M:%S)
smt -l                      # list all available timezones
smt -v                      # show version
