+# Configure The Timezone
+
+Running `show timezone;` will reveal the timezone for your postgres
+connection. If you want to change the timezone for the duration of the
+connection, you can run something like
+
+```
+> set timezone='America/New_York';
+SET
+> show timezone;
+ TimeZone
+------------------
+ America/New_York
+(1 row)
+```
+
+Now, if you run a command such as `select now();`, the time will be in
+Eastern time.
