Thanks, I was wondering about ext4 and time stamps.
I wonder what the zfs/btrfs type file systems do. I am a bit lazy to check but I expect btrfs is using 64 bit. zfs, I would not be surprised if it matches zfs (edit meant ext4 here).

So 580 years or so till problems (but probably patchable ones? I believe the on disk format is already 2x uint64s, this is just the gethrtime() function I saw).

it is convenient unit because 10^9 fits neatly into 32 bit integer, and it is unlikely that anyone would need more precision than that for any general purpose use.
