Someone who is a Raspian expert can correct me on this if I'm wrong: I seem to recall that Raspian, if stripped of fake-hwclock, etc., does NOT start up with the universal Linux Jan 1970 date but uses a date that corresponds to the release date of that version of Raspian. This means that programs/scripts that rely on looking for an "old" date (say, pre-2000 or pre-1990) as an indication of a 'bad' time setting won't work properly.
However, I can't remember where I stumbled on this nor does a quick Google search help me. I don't want to spread bad information. Can anyone confirm/refute this?
