Now the IOC time is synchronized with the NTP server and works well. But there is still the problem.
Here is the message(by the way: The waveform PV has 2048 points (double value), and the updating frequence is 25HZ):

> By default a VxWorks IOC tries to synchronize its OS clock with an NTP server running on its boot host, but if you have NTP available from a different IP address you can configure that by setting the environment variable EPICS_TS_NTP_INET. You may also need to set the EPICS_TIMEZONE variable to your local timezone, see the comments in the base/configure/CONFIG_SITE_ENV file for details of the format of that variable.
