If you want to ignore everything you've been told and do not want to print directory names in order of date of creation and instead want to print directory names in order of increasing file status change times, you can use:
Code:
ls -1cd /home/test/*/

(note that the 1st option in the above command is the digit 1; not the lowercase letter l). Using the -1 option tells ls to produce names one per line without needing to feed the output through a while read echo loop.

If your directories are located on a filesystem type that does save creation times in addition to file status change times, on some systems you could get a list of directories in increasing order of creation times with:
Code:
ls -1Ud /home/test/*/

but since standard filesystems don't have a creation time (only a status change time as drl mentioned), the option letter to print the creation time (if there is one) may be different on your system. Search the ls man page on your system for an option containing the word creation to see if there is an option to sort output by creation time on your system, and if there is, what option character invokes it and what filesystem types have that information.

fatsort

fatsort(1)						      General Commands Manual							fatsort(1)

NAME

       FATSort - FAT filesystem sorting utility

SYNOPSIS

       fatsort [options] device

DESCRIPTION

       FATsort sorts directory structures of FAT filesystems.  Many MP3 hardware players don't sort files automatically but play them in the order
       they were transmitted to the device. FATSort can help here.

OPTIONS

       -c     This option causes FATSort to ignore the case of filenames (e.g. 'example.mp3' is equal to 'EXAMPLE.MP3').

       -f     Force sorting even if the device is mounted or if FATSort cannot determine if the device is mounted.

       -h     Shows some help information.

       -i     Prints some file system information of the specified device.

       -l     FATSort will not sort directory structures, but just print the current order.

       -o type
	      This options specifies how FATSort will sort files and directories.  type can be 'd' for directories  before  files  (which  is  the
	      default), 'f' for files before directories, or 'a' for no differentiation between files and directories.

       -n     Uses natural order to sort directory structures instead of  alphanumeric order.  For example, an alphanumeric order would be
		     file123.mp3
		     file21.mp3
		     file3.mp3
	      and the corresponding natural order would be
		     file3.mp3
		     file21.mp3
		     file123.mp3.

       -q     FATSort will work quietly without printing additional information messages.

       -r     Sorts the directories in reverse order (Z-A).

       -R     Sorts the directories in random order.

       -v     Shows version information only.

       The following options can be specified multiple times:

       -d directory
	      Sort directory only

       -D directory
	      Sort directory and all subdirectories

       -x directory
	      Don't sort directory

       -X directory
	      Don't sort directory and all subdirectories

       -I prefix
	      Ignore  filename	prefix	prefix	during sorting. For example, passing option -I "the " tells FATSort to sort 'The Beatles.mp3' like
	      'Beatles.mp3'.

EXAMPLES

       Sort FAT filesystem on an USB stick:
	      fatsort /dev/sda1

       Sort FAT filesystem in a file:
	      fatsort /home/user/fat16_fs.img

       Sort directory /dir1 and all subdirectories except /dir1/dirA:
	      fatsort /dev/sda1 -D /dir1 -x /dir1/dirA

       Ignore prefixes 'a ' and 'the ' during sorting:
	      fatsort /dev/sda1 -I "a " -I "the "
