    keyword=re: Sync Checks not quite right for Run 1597

    It's a discontinuity in the time between scaler reads (see figure). This glitch shows up for all ROCs so we're still in sync, I think.

    I'm not sure why it's happening though.

    Bob, Bryan, Vince: can you comment on what might cause this? I understand that there is "slop" in the mean time between the scaler reads, but this seems pretty big. Perhaps a network stall? A glitch in the roll-over handling code (unlikely)? Could it be related to the 'really high single scaler read' glitch mentioned that's been noted since last night?
