If you want to display the date the node was posted or created when showing fields, you don't need to use a token. Simply add the field
Content: Post date to the fields of the view.
If you want to include this date in a
Global: Custom text field in your View, be sure to have the field
Content: Post date above the
Global: Custom text field. The replacement pattern for the post date will appear by clicking on
Replacement Patterns inside the custom text field (usually named
[created]). You can also select
Exclude from display in the post date field if you don't want it to show.
Re-read your question, and I guess you are using Token Filter to insert tokens like
[node:created] in a
Long text field in your node, right? If this is the case, I'm afraid Views will not do a token replacement when rendering the field. There may be a way to modify the Views formatter to do this, but that's beyond my skills. See this post for a similar situation - you are able to use token replacements in your Views Header or Footer custom text, but not in a Field.
