The editing bits were actually kinda cool for me. At first I thought it was an edit error, then I wasn't sure, then I was, but they didn't hurt the story. I get interrupted often enough at work that I rewind now and then, so it was the same.
The part that DID bug me was the line to the effect of "There is no system for changing the ships time." That line almost killed the story for me. If you deleted that line, the story would have worked a lot better. If he KNEW that, then he'd have to wonder how the time did change. Obviously, he was crazy, but still, he'd ignore that fact, not tell it in the story. He also could have said 'I can't believe he found a way to edit the time, there isn't a built-in way, or something like that. Perhaps he could have realized after he vaped Richard that, wait a minute, there isn't a way to change the time, what have I done!
All that aside, if I imagine how the story would have been without that line, I did enjoy it. I wasn't surprised by anything, but a story doesn't need a surprise to be good.
