The picture you provided, simply shows the last check time of your services and the last time the host\service status dashlet updated from the database. These times are not comparable in any real way. The host\service dashlets in the upper right, only update the time when the update from the database to reap new results, it says nothing about when your last checks were. The service last check time, is perfectly understandable if you have 1 hour check intervals, but I could not know if that is actually the case without seeing your configurations.

Run the following commands:
Let me know if this fixed your issue.

I try the command but the problem still appear. please note that this problem appeared when I changed server time to summar time, but nagios XI time not changed

What changes exactly did you make? Can you post screenshots or provide the line in a config file?

I applied the following commands

service nagios stop
killall nagios
service ndo2db stop
service ndo2db start
service nagios start

But how did you change the time? What specific edits did you make? That might have an impact on how things are working.

I followed the steps in change time manual:

Couple of questions:

What are the check intervals for the checks that you displayed originally?
What timezone is your desktop system in, and is that different from the timezone that nagios is in?

Also as I mentioned previously, the times that you mentioned are completely 100% separate. The last updated time in the upper right is a time created on your local system showing when that dashlet last updated. It actually has no bearing on when core or XI runs or displays items. Also due to that being created via javascript, it uses your desktop system time, not the nagios system time, so if there is an hour difference, as it appears from your screenshot, it should be fully expected that these are different. Secondly the last check time, is just the last time nagios ran a check for that particular host or service. This time is calculated locally to the nagios system and should not be generated on your desktop, so again if they are in differing timezones, it will definitely differ on your screen.
