Can you believe it, only 30 years left until the Y2K38 bug! Incase you aren't familiar with this buy it's that past the date of January 19th 2038 all 32-bit systems will reset back to 1901! This is not a flaw in any Operating System, everyone is affected! Altho by that point there will (hopefully) not be any systems still on 32 bit. Also if you are trying to get a 30 year loan after today there may be problems with the accounting systems.
I found this link that should help anyone understand what I'm talking about.
