   [CLOCKS] SECOND CHANGE

Dear PuzzleUp Contenders,

To clarify the meaning, the question text has been changed.

Old: "...What is the time when this first happens?"

New: "...What is the time when this first happens after they are set?"

Please take notice and submit your answers accordingly.

Regards,

   [CLOCKS] Clarification

Hi Puzzleup folks,
The conditions are met immediately when you start observing, at 12:00. You may wish to eliminate this answer by stating that the clocks begin their motion and THEN you start observing.
Nice problem...Thanks!
