Hello!
I installed mrfioc2 2.3.0 on MTCA platform. According to EVR Usage Guide, when I do the timestamp test, there are two problems:
a. The system is configured with NTP, but the current time provider does not have NTP
[opi@localhost ~]$ ntpstat
synchronised to NTP server (202.38.64.7) at stratum 3
   time correct to within 11 ms
   polling server every 512 s
b. The time interval between the system clock and the EVR time is large.
epics> generalTimeReport(2)
Backwards time errors prevented 446106 times.

Current Time Providers:
    "EVR", priority = 50
	Current Time is 2022-03-07 16:34:25.575015.
    "OS Clock", priority = 999
	Current Time is 2022-03-07 16:36:55.978638.

Event Time Providers:
    "EVR", priority = 50

Thank you for your time. I am looking forward to your reply.
