What, Really?? 48 years ago and still alive! What a strange bug
I think that is related to the Unix “epoch time” (01/01/1970), that is coincident: 48 years ago.
how it is possible strange it is!
Maybe a particular date+time wasn’t set or was set to some sort of null date+time, but then a particular calculation was run on it to find how long it was between now (current date+time) and that date (and time). Because of the Unix “epoch” time (set to Jan 1st 1970 - ie. it could think the null/unset date/time is this), the answer could be about 48 years.
