What time is it?

This morning my flatmates and I were puzzled about the time. As we have now shifted to wintertime and clocks have to be adjusted (no, I didn't wake up at 4 am just to adjust my clock) we had no idea about the correct time.

The computer screen displayed different time than the mobile phone indicated and vice versa. In the end we figured out the correct time by comparing our electronical devices.

10 minutes after, while sitting in my room, I remembered that my alarm clock and watch would have been very helpful with that, because I have to adjust them manually. I haven't done that yet, so instead of relying on electrical machines I should have taken a good look of my old wrist watch before determining anything.
