Topology: NTP server――NE80-1――NE80-2. NE80-1 traces NTP server time and NE80-2 traces NE80-1time. After NTP configuration is finished, NTP on NE80-1 and NE80-2 can synchronize, but the time on the router is eight-hour earlier than Beijing time.
On NE80 configure clock timezone BJZONE add 08:00:00. Add eight hour based on Greenwich time. After the change, the problem is solved.
Check NTP on NE80 and the state is synchronized. It indicates that NE80 has traced NTP server time. This NTP server also serves WAP and color ring service. These networks are normal. It indicates that NTP server is normal. The problem is related with time standards of NE80. Default clock time on NE80 is Greenwich time. The time difference is just eight-hour.
