I wouldn't write most BSD, Linux and UNIX systems do not save a file creation time.

FreeBSD traditional file system is UFS2 and the trend is to switch to ZFS. Both of these file systems store the file creation time.
Linux default file system on many distributions is ext4 which stores file creation time too. Some alternatives like btrfs and ZFS do also store it.
OS X main file system is HFS Plus and it is transitioning to APFS, both store the creation time.
On the Unix side, Solaris, AIX, and HP-UX respectively default to ZFS, JFS, and VXFS. All three do store the creation time.

An exception is OpenBSD with FFS2.

Given the unfortunate lack of standard for this feature, the ways to retrieve that piece of information will vary depending on the OS. That might be ls, the non standard stat command, or something else.

mvdir

mvdir(1M)						  System Administration Commands						 mvdir(1M)

NAME

       mvdir - move a directory

SYNOPSIS

       /usr/sbin/mvdir dirname name

DESCRIPTION

       mvdir  moves  directories  within a file system. dirname must be a directory. If name does not exist, it will be created as a directory. If
       name does exist, and is a directory, dirname will be created as name/dirname. dirname and  name may not be on the same path; that  is,  one
       may not be subordinate to the other. For example:

       example% mvdir x/y x/z

       is legal, but

       example% mvdir x/y x/y/z

       is not.

OPERANDS

       dirname	  The name of the directory that is to be moved to another directory in the filesystem.

       name	  The  name  of  the directory into which dirname is to be moved. If name does not exist, it will be created. It may not be on the
		  same path as dirname.

USAGE

       See largefile(5) for the description of the behavior of mvdir when encountering files greater than or equal to 2 Gbyte ( 2^31 bytes).

EXIT STATUS

       0     Successful operation.

       >0    Operation failed.

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |
