I keep seeing this (more here and here) unit (maybe solely) in Boeing test airplane cockpits above the autopilot panel. Can someone tell me what is this and what the purpose of this big unit? Based on this video the center display tells you the time (UTC?) but cannot figure out the purpose of the 2 side displays. Not to mention having a clock in the cockpit does not require a huge unit like this I assume even in aircraft safety terms with being spark proof...).
Also would be interesting to know what is that small black panel to the right of the bottom FMC here. Looks some buttons have arrows, maybe camera control panel?
