@vfrmedia @MightyPork the article is 15 years old, hm, I have a cheap temperature sensor at home that also has clock and gets it from air (i know it's not a technical term, but...) and it's really hard for it to catch it even on my window in the 4th floor
I mean, I could just get NTP, right. It's quite frustrating to test time based OTP codes when all your machines have some random time.
