Unsure why access time on a directory isn't changing
Hello... And thanks in advance for any help anyone can offer me
I was trying to work out the differences between displaying modify, access, and change times with the 'ls' command. Everything seems in order when I look at files, but the access time on a directory doesn't seem to change when I expect it too.
I'm sure I must have the concept misunderstood with a directory... But when I 'cd' to a directory like 'Downloads' or do an 'ls' to view it's contents... And then look at it's last access time with 'ls -ldu' or 'stat'... It does not change
It has changed when I wasn't paying attention and has a date/time from yesterday... I just don't understand what would caused it to change
Can someone straighten me out here? THANKS!

utimes(2) System Calls Manual utimes(2)
NAME
utimes - set file access and modification times
SYNOPSIS
DESCRIPTION
The function sets the access and modification times of the file pointed to by the path argument to the value of the times argument. The
function allows time specifications accurate to the microsecond.
For the times argument is an array of structures. The first array member represents the date and time of last access, and the second mem-
ber represents the date and time of last modification. The times in the structure are measured in seconds and microseconds since the
Epoch, although rounding toward the nearest second may occur.
If the times argument is a null pointer, the access and modification times of the file are set to the current time. The effective user ID
of the process must be the same as the owner of the file, or must have write access to the file or appropriate privileges to use this call
in this manner. Upon completion, will mark the time of the last file status change, st_ctime, for update.
RETURN VALUE
Upon successful completion, 0 is returned. Otherwise, -1 is returned and is set to indicate the error, and the file times will not be
affected.
ERRORS
The utimes() function will fail if:
Search permission is denied by a component of the
path prefix; or the times argument is a null pointer and the effective user ID of the process does not match
the owner of the file and write access is denied.
Too many symbolic links were encountered in resolving path.
The length of the path argument exceeds or a pathname component is longer than
A component of path does not name an existing file or path is an empty string.
A component of the path prefix is not a directory.
The times argument is not a null pointer and the calling process' effective user ID has write access to the file
but does not match the owner of the file and the calling process does not have the appropriate privileges.
The file system containing the file is read-only.
The function may fail if:
Pathname resolution of a symbolic link produced an intermediate result
whose length exceeds
