/bin/stat from Busybox prints zero fractional seconds for mtime, atime and ctime. For example, on default install of Alpine Linux:

    touch /tmp/test
    stat /tmp/test

Output:

    File: /tmp/test
    Size: 0 Blocks: 0 IO Block: 4096 regular empty file

Compare to /bin/stat from coreutils on the same system:

    File: /tmp/test
    Size: 0 Blocks: 0 IO Block: 4096 regular empty file

Apparently, Busybox deliberately prints zeros instead of the real fractional seconds: https://git.busybox.net/busybox/tree/coreutils/stat.c?id=e2026381bed88e79b6f7657eef8319e60ff83041#n166. Is it possible to fix this? This is confusing since the output isn't just missing data but contains incorrect data. When seeing the output with 000000000 for fractional seconds, one can reasonably take this to mean that fractional seconds are zero.
