Nailing dense questions about network infrastructure? You get to the engineering team.
Failing to know what the "G" in 2.4GHz means? You probably just need someone to tell you to restart your router.
Before the ubiquity of watches, time was announced using church clocks and bell strikes. There's a big bell for hours (low pitch) and a smaller one for announcing quarters (higher pitch).
Signalling zero is not possible using "zero bell strikes", so 00:00 is signalled by 4 strikes of the quarters bell and 12 strikes of the hour bell.
Thus, the sequences go like:
11:15 1x quarter bell
11:30 2x quarter bell
11:45 3x quarter bell
12:00 4x quarter bell + 1x hour bell
Basically it makes sense then as all the quarters belong to the same hour.
Something using solar for power, with a rugged and water-resistant enclosure, made of extremely high-quality components that won't break for hundreds of years at least. Maybe add an IRDA port for good measure, to make it possible to transfer all the data out somewhat quickly.
You could make hundreds of these and put them in hard-to-reach locations around the world, to make sure at least one survives whatever calamity might befall us in the future.

I have many current and old dumps and can switch between a few years. Very nice in case of deleted articles or to check old time stamped versions. It also supports more than just Wikipedia like wikiquote or wikivoyage or cooking wiki. You can compile own mediawikis too
