A weird bug on Facebook is congratulating people on 46 years of friendship — even though most of them are younger than 46 and the site has been around for less than a quarter of that time.
This is probably the result of something called "epoch time," which is a way the Unix operating system records time. Epoch time is the number of seconds that have elapsed since midnight on January 1, 1970.
