**9.00 am.** Take each hour-pip in turn and note how many other pips are numbered
correctly in relation to it.

There are two sets of three pips correctly numbered with respect
to each other *1, 4, 9* and *2, 5, 12.*

There are four pips, numbered *6, 7, 8, 10 *that do not
relate to any other pip.

There is only one set of two related pips *3 and 11*.

The traveler was told that he could tell the time if he knew
how many pips were correctly numbered.

The pips
numbered *3 and 11* (a unique set) must be correct otherwise
the traveler would have had a number of choices (2 sets of 3 related numbers,
and 4 individual numbers)..

Counting counter-clockwise from pip number 11 shows the hour hand pointing to what would normally be 9:00 o'clock, confusingly re-numbered as 2.00 o'clock. The traveler was also told that 12:00 o'clock was no longer at the top of the dial face, so he now knew that the dial face had been rotated 90° counter clockwise.

The traveler met the passer-by in the morning, hence the time is 9.00am.
