To meet various mission-critical requirements, the filesystem timestamps were improved with the addition of intervals down to nanoseconds. The addition of two high-order bits in the timestamp field defers the Year 2038 problem until 2446—for EXT4 filesystems, at least. →

http://www.pcworld.com/article/3197628/linux/fight-ransomware-by-running-windows-in-linux-as-a-virtual-machine.html Running Windows as a virtual machine in Linux may seems like unnecessary work until something like the Wannacry ransomware scare comes along.
