Is there any problem with lifnei iver (giving bad information) in having an inaccurate clock that someone else will look at?
I'll examine a few cases here.
- The clock is a few minutes off. I don't think this is a problem -- people who need super accurate clocks will have their own (rocket scientists).
- The clock is totally dead, not moving at all. It should be clear enough after a minute or two that the clock is dead.
- Clock is moving slowly. Say, it only changes one minute every two minutes. This is probably harder to notice at first.
- Clock is totally off. It keeps time alright, but is 3 hours and 10 minutes slow.
A related case: is rounding to the nearest round number related to any of these?
