Lol. The issue has been a topic of discussion in Tech since 1970 ! But I just brought it up to put it in perspective with all the countdown clocks set to 3 November 2020
I remember in college (1980’s) wondering what would happen then the clock ticks went over the biggest number that could fit in 32 bits.
I calculated it was 2036 and that seemed SO FAR away at the time...
