 ## Working with time zone parameters
 If you plan to work with date and time data in PostgreSQL, you’ll want to ensure that you’ve set the correct time zone for your location. All timezone-aware dates and times are stored internally in PostgreSQL in UTC. They are converted to local time in the zone specified by the **TimeZone** server parameter before being displayed to the client.  This parameter can be edited on **Server parameters** page as explained above.
