I am running on windows, so the directory structure here is for Chrome on WIndows 11.

If you look in the directory C:\Users\username\AppData\Local\Google\Chrome\User Data\TrustTokenKeyCommitments, there is a subdirectory with a date that holds a series of files that seem to be for Private State Tokens (the keys.json file certainly holds PST data). But note the dates on the files in the picture. They are "12/31/1979". Is this intentional and, if so, why. And if not, is this some kind of bug?

I am writing about PSTs in www.theprivacysandbox.com and want to make sure I address this correctly.
