+
+The timezone by default on the server is UTC.
+
+If you want to make it so that your shell prints out dates in localtime for you, run `tzselect`
+to find the correct timezone name that you'll need to export as the `TZ` environment variable.
+
+for example, if you're in eastern time, add something like this
+`export TZ="America/Detroit"`
+
+to your `.bashrc` .
