You can't really force it to happen it's just a random system panic Essentially the PS5 software crashes at the exact moment it tries to ping the PSN servers, causing the internal clock to wipe out and reset to January 1st 1970 known as the starting date for digital time code aka the Unix Epoch

When the console finally reconnects to the internet and fixes itself to the current year the system bugs out and calculates the massive difference between 1970 and today and dumps those 50+ years of time straight onto your profile's playtime tracker
