1、First modify the following files：
#vim /etc/cron.daily/timeupdate
ntpdate ntp.ubuntu.com
#chmod 755 /etc/cron.daily/timeupdate
#sync
#date ( Type 'date' to check the time )
2、Then booting the board to test：
a).In the case if the board has no cable that will stop at the boot such as：
eth0: device MAC address fa:44:18:40:0c:01
Since the board has no cable ，file system is waiting for assigning IP address，if the board connects the network cable ，the problem will not exit.
b).Assigns MAC Address：
#cat /etc/network/interfaces.d/eth0
auto eht0
allow-hotplug eth0
iface eth0 inet dhcp
hwaddress ether fa:44:18:40:0c:01
#vim /etc/cron.daily/timeupdate
ntpdate ntp.ubuntu.com
#chmod 755 /etc/cron.daily/timeupdate
#sync
#date ( Type 'date' to check the time )
