Description Dominique Liberda 2022-12-25 13:42:49 UTC 
In case of an abnormally high date stored on the fs, busybox's ls -la crashes on trying to display it. I have experienced this when interfacing with an NTFS3 filesystem which has invalid dates stored in some of the file metadata.

```
(gdb) r -la
