+title: "Bash Snippet: CLI World Clock"
+date: 2019-03-18T00:00:00+02:00

+
+When working in a global organization, colleagues are all around the world!
+And thus answering to *"What time is it in their timezone?"* becomes a frequent
+task. I initially used an online service for this but it is cumbersome and
+requires me to leave my terminal.
+
+Let's meet the CLI World clock!
+
+```sh
+function t() {
+  for tz in Europe/Paris Europe/Dublin US/Eastern US/Central US/Pacific; do
+    echo -e "$tz:\t$(TZ=$tz date -R)"
+  done
+}
+```
+
+You can copy/paste this snippet in your terminal or add it to your `.bashrc`
+to have it handy on every open terminal.
+
+Each time I want to know which time it is for my colleagues, I run the `t`
+command:
+
+```raw
+$ t
+Europe/Paris:    Mon, 18 Mar 2019 18:33:49 +0100
+Europe/Dublin:   Mon, 18 Mar 2019 17:33:49 +0000
+US/Eastern:      Mon, 18 Mar 2019 13:33:49 -0400
+US/Central:      Mon, 18 Mar 2019 12:33:49 -0500
+US/Pacific:      Mon, 18 Mar 2019 10:33:49 -0700
+```
+
+The timezones used here comes from `/usr/share/zoneinfo/`.
