When is “I” if not Right Now?

Q: I really can’t disprove this "I." I keep looking, and find nothing. But does that mean it’s not real?

A: According to you, you look right now and find no "I."

Right now is the only time there is. So if you can't find "I" now, when do you think you might find it? 

If "I" is not here right now, then how can it ever possibly be? You can't find it now. Now is all there is. Can you ever find it now? Have you ever found it now? Do you think there is some other now that "I" might be found in? 

Is there such thing as an other NOW?
