Y2K38 Watch Starts tomorrow

Train TracksTomorrow marks the beginning of the 30 year countdown to the Y2K38 bug.

Ok, let’s see if I can lose you here.

Most computer systems calculate time in the number of seconds since January 1, 1970. When calculating January 19, 2038, 03:14:07, it is 11111111111111111111111111111111 seconds in binary. On a 32 bit system, one second later wraps around to 0 which equals January 1, 1970 (which is bad for calculations.) A 64 bit system has another 32 0’s in front of those 32 1’s and won’t wrap around.

So, when you’re refinancing your 30-year mortgage this weekend, you’ll know exactly what’s going on when they say, “We’re having computer problems, can you come back Monday?”
