On page 20 of the new F21 System Administrators Guide is how to use timedatectl to adjust the system and hardware clocks. But it gives me an error message saying "Invalid number of arguments."

[root@cygniapolis ~]# timedatectl set-time 2014-12-10 15:40:30 Invalid number of arguments.

What am I doing wrong here? My CMOS battery is dead so until I have it replaced I need to set the clock every time I start up. Thanks.
