Follow-up Comment #1:


> [...] cannot use the tests [...]

This is rather brief and vague.

Please expand on:
- what did you try to do? -> test setup
- how did you try to do it? -> command line
- what was the outcome?
- what was your expectation?
Please provide a small reproducer.

Other than that, I see here that the -ctime/-atime tests are working as
expected:


# CTIME: no output yet.
~/tmp> find -maxdepth 1 -type f -ctime -1

# ATIME: no output yet.
~/tmp> find -maxdepth 1 -atime -1

# Read a file -> atime should change (... usually).
~/tmp> cat LICENSE > /dev/null

# Change permission bits of the file -> ctime should change.
~/tmp> chmod 0600 LICENSE 

# CTIME: works.
~/tmp> find -maxdepth 1 -type f -ctime -1
./LICENSE

# ATIME: ...
~/tmp> find -maxdepth 1 -type f -atime -1

# oops, no output, why?
~/tmp> findmnt /home
TARGET
      SOURCE    FSTYPE OPTIONS
/home /dev/sda3 ext3   rw,noatime

# -> ATIME does not work on /home (here) because it is mounted with the
'noatime' option.

# On another file system with 'relatime' instead of 'noatime' also -atime
works:
/tmp/mpoint/tmp> find -maxdepth 1 -type f -atime -1

/tmp/mpoint/tmp> cat LICENSE >/dev/null

/tmp/mpoint/tmp> find -maxdepth 1 -type f -atime -1
./LICENSE

/tmp/mpoint/tmp> findmnt /tmp/mpoint 
TARGET      SOURCE     FSTYPE OPTIONS
/tmp/mpoint /dev/loop1 ext4   rw,relatime
