+   Uses the =my.location= module to determine the timezone for a location.
+
+   This can be used to 'localize' timezones. Most modules here return
+   datetimes in UTC, to prevent confusion whether or not its a local
+   timezone, one from UTC, or one in your timezone.
+
+   Depending on the specific data provider and your level of paranoia you might expect different behaviour.. E.g.:
+    - if your objects already have tz info, you might not need to call localize() at all
+    - it's safer when either all of your objects are tz aware or all are tz unware, not a mixture
+    - you might trust your original timezone, or it might just be UTC, and you want to use something more reasonable

+   ]
+   #+end_src
