Last opened date mystery

[MiniMacDonald]

Hi All
I am a new Mac Mini owner, specifically the 2018 release with latest Mojave update. My question is, "Has anyone noticed when one opens a Drive Info page that under More Info: the Last Opened date is December 31, 1969. What is that all about?"

It's probably just the default last opened date when the drive has never been used before.

That's the beginning of Unix epoch time, before the big bang if you will. 1/1 1970. Unix time is measured in seconds after the epoch.
