whatever の時制

This is not a piece of advice to you I'm talking to myself for my practice of writing skills.
I'd put these words ( Does the word 'whatever' have any regulation of the tense? ) into Google's inquiry box and tap return key. I'd get several site URLs. I could select and judge suitable one.
I suppose the word 'whatever' has no regulation of the tense.
