Oh, it means that if you DROP the type it will leave some stuff behind.
You can ofcourse handle *value* of that type just like any other value.
The 'tag table' in this case would be the list of timezones. I'll see
if I can clarify it.

Well, you can index them ofcourse, but you need to indicate explicitly
what you want to index: the timestamp or the timestamp shifted to the
timezone. I felt the module couldn't make this decision on its own.
Indexing the type directly would be more work, not sure if there's
enough demand for it.

Have a nice day,
