Fixes #17063 Add modification time display to ls -l long format output. The timestamp is shown as 'YYYY-MM-DD HH:MM' between the permission string and the file size, following the ISO long-iso format. Files with st_mtime == 0 (e.g., procfs, tmpfs pseudo-entries) skip the timestamp display to avoid showing a meaningless epoch time. Signed-off-by: hanzhijian <hanzhijian@zepp.com>

The
ls -lcommand now shows the modification time (st_mtime) inYYYY-MM-DD HH:MMformat (ISO long-iso style) between the permissionstring and the file size.
Files with
st_mtime == 0(e.g., procfs, tmpfs pseudo-entries) skipthe timestamp display to avoid showing a meaningless epoch time.
Changes
nshlib/nsh_fscmds.c: Add#include <time.h>and timestamp displaylogic in
ls_handler()after the permission details output.Verification
Built and tested on
sim:nshconfiguration.ls -l /:
ls -l /data:
ls -l /proc (procfs, st_mtime == 0, timestamp correctly skipped):
ls -l /dev (pseudo-devices, st_mtime set to boot time):
rtc0hasst_mtime == 0so the timestamp is correctly omitted.Signed-off-by: hanzhijian hanzhijian@zepp.com
