Why does my phone have the wrong install date for system files?

[Sparkybalboa7018]

All of my phone's system files are dated December 31, 2008 as their install date.
I've had this occur to separate models including a S10e, Note 8, and now a Moto G stylus.

How are you inspecting the files to determine the install date?
