I recently spent a few days in the area and heard a lot of Chronos callsigns doing training. Not like a single annual check, like I was on with Portland approach for 3+ hours/day for 4 days and there was always at least one Chronos plane doing training. I deduced that there must have been a new hire class, which I was happy about, but it seems I guessed wrong. Back to bothering the HR lady each month with updated times.
