I lose time in a couple of different ways. One is that "Time Warp" you've described. I blink and the clock has jumped ahead and hour or four. There is a different feel to it, than the "lost track of time" kind of loss.
The time didn't just slip by. It's gone. No memories, no sense of time passing.
I lose time in front of the PC, like anyone, but sometimes at night I "come to" as the computer is shutting down two or three hours after my last memory of checking the clock. Occasionally I find different things DL'd on to my drive I don't want there.
I frequently draw a total blank when asked things like "You're name?" Numbers, address, and so on. I can usually get it back with some kind of clue. So I check in my wallet.
I have lost days. Again there nothing there that says time has passed.
I had done drunk, and drugged, beaten up, and exhaustion to the point of hallucination. So I know the difference.
Any time loss scares me. But loosing entire days, or more than one, freaks me out.
So, um. Yeah that happens to me.
