Stop the cap your honor. There is not a single filesystem that prevents you from using colons in filenames except exfat, I went ahead and checked and ext4, xfs, btrfs, zfs, and even reiserfs let you use any characters you want except \0 and /.

And I fail to see why bumping the epoch would ever be a problem. Using the epoch not a reason why its bad.
