Hello, I have zabbix 4.4 installed and worked correctly for a long time.
Yesterday ran "yum update" command (CentOS 7.7.1908) and updated everything with no errors.
Immediately after the update, I found all graphs drawing several minutes lag from the real time.
Now the version is 4.4.4
I know the previos version was 4.4.*, but don't know which one exactly.
You can see that zabbix knows correct current time, but draws with delay.

I've checked:
System time: command "date") - correct
php time: echo date("H:i:s"); - correct
mysql time: select now(); - correct
MySQL load is very low
Administration -> Queue in zabbix GUI - all the zeros.
What else could be wrong and what can I check?
