Title says it all. What happened here? November 17th 2013 at 9pm was not 10 years 5 days and 22 hours ago.

I personally saw that happen a few times on my profile as well.

Yes, the calculations are a bit imprecise. I think they don't account for leap years and other exceptions of the globally used date/calendar system.

Ahh yeah... That makes sense. Leap days never feel like they matter until you see their effect over the course of a large amount of time I guess... That's wild. The way they do it honestly makes sense. It's more accurate.

Two leap years in a 10 year span accounting for two extra days of completion time makes sense, but something wonky is happening with completion times for me. Tangentially related, my profile page says I got the Spider-Man 2 platinum in 3 weeks, 1 day, but when you click into the SM2 game page from my profile, it shows the correct completion time of 3 weeks, 3 days. (By the way, if you are going to double check for yourself, you have to add an hour to the completion time because daylight savings ended during my completion of SM2, adding an hour of real time).
