It doesn't change the file's last modification time for me using /bin/sh:
# uname -r
6.1-RELEASE
# ls -l aaa
-rw-r--r-- 1 root wheel 512 Jul 18 17:00 aaa
# :>>aaa
# ls -l aaa
-rw-r--r-- 1 root wheel 512 Jul 18 17:00 aaa
# date

So ':>>${FILE}' isn't the same as 'touch ${FILE}' for existing files.
Sincerely, Dmitry
