Github user fhueske commented on the issue:

    Thanks for the review @twalthr.
    I've updated the PR. 
    @haohui: This PR preserves the current logic that time attributes are exposed as `TIMESTAMP`.
I agree that support for time indicators that expose themselves as `Long` is desirable. However,
this requires quite a few changes as we need to extend several functions (incl. `TUMBLE`,
`HOP`, etc.) and validation logic in some operators (over windows, joins, etc.). So this is
not a lightweight change and should be done as a separate issue, IMO.
