It's this weekend for us... but nowadays all things technological reset for you, happened many times when I didn't know it was time for "fall-back" or "spring forward" and I looked at a computer or cell and I noticed the time change... I realized it wasn't a case of missing time in an alien abduction quite fast though.
Yeah, tech does indeed resets itself. However I do have a "non-smart" clock radio in my room as well as a standard watch. So it's those that can potentially set me off balance.
You mentioning missing time and alien abduction has reminded me of this time years back. I fell asleep at about midnight but then was woken up with the house alarm going off. Looked at the clock and it was flashing a few minutes past midnight. Now I knew I was out for longer than that. So I checked my watch which was showing 11:30pm. By now I was thinking has there been a nuclear burst nearby and the resulting EMP knocking the time pieces off kilter? Then I headed downstairs, walked into the kitchen to see my brother standing there angrily slamming the door of the oven shut muttering the words "look at this, my duck's ruined" before walking out.
Transpired the time was actually around 3am in the morning and I had probably just entered the Twilight Zone.
