Remove incorrect tokens.

I can't reproduce the error. For me it correctly returns the timestamp value.

@joevagyok, it seems that this problem was already resolved in another way. But value and end_value are displayed in html_datetime format.
Also, at the moment, I do not see a problem that the date can be displayed in html_datetime format from these fields, and not start_date or end_date, although based on the logic of the module, it should be displayed taking the timezone as well, but it seems that this is not used in the value and end_value fields.

@joevagyok, it may even be possible to simply close this task, since there is no longer any work required here.

Thanks for clarifying it. Closing this issue.
