You can click    to make sure that the NTP server is connected. 
Note: 
If  the  camera  is  connected  to  a  public  network,  you  should  use  a  NTP  server  that  has  a  time 
synchronization  function,  such  as  the  server  at  the  National  Time  Center  (IP  Address: 
210.72.145.44).  If  the  camera  is  set  in  a  customized  network,  NTP  software  can  be  used  to 
establish a NTP server for time synchronization.
