This is how I know you-are-all-slackers and not advancing the power of linux:
Given the decaying memory of all biological entities, including humans, the 'stack' and the ordering that it gives is central to any process: from making a cheese & onion sandwich to computing.
The ordering/recentcy provided by the stack demands a RTC. The need to reset the RTC of the rPi on every reboot would be acceptable, if this was obviously easy.
Consider: M$:DOS `date`:-
- shows what its current value is;
- shows a *VALID SYNTAX* to be easily copied to update, if required.
In contrast *nix: `man date` is 196 lines long !!!
Must each of us zillion slaves break off his important tasks to research the required syntax for this essential RTC setting. I did that wastefull brain-numbing exercise 5 years ago - and forgot it.
An example of why date stamping files is essential is: when trying to recover yesterdays in a directory which has plenty old *.pdf & *BIG.wav ..etc. files. You can't just see the new files ; and searching is painfull, uneconomical and STOOPID.
How many million rPi & similar need to find victims before they write a 1-liner: Date, which EASILY allows any fool to set the RTC?
And put the damned label on the front of the bottle - not inside.
Forget about multi-cores and over-clocking. It's the boring, trivial details that makes the big difference.
rPi is rather successful because of the 'eco-system' it's got; which could never be 'built' in most of the rest of the world.
