I decided to re-install by Pogoplug V4 with Alarm. When I was configuring netctl for ntpd, following the wiki page:

To synchronize your system clock along with a network connection through the use with Netctl. You can append the following line to your netctl profile.
ExecUpPost='/usr/bin/ntpd -q || true'
Note: The -q flag forces ntpd to set time once and quit, i.e. the daemon will not be started. If the operation is unsuccessful, your system clock will not be synchronized. See Running as a daemon for an alternative approach.
