The time stamp when the log acquired by Zabbix agent is stored in the "HISTORY" is not the time stamp on the Zabbix server side, but the time stamp when it is sent from Zabbix agent.

However, this specification has major problems.

For security reasons, intentionally disconnect the monitored host from the network and restore communication after resolution. Then, the time stamp of the log stored in "HISTORY" of Zabbix server will be the time (past) at the time of occurrence instead of the present. As a result, it is not possible to know when the log was stored in "HISTORY" of Zabbix server.

Also, the event displayed in "Problems" suddenly appears to have been inserted in the past rather than the occurrence of the current time. There was no description of this specification in the reference, which caused a great deal of confusion when investigating the failure.

Since it is divided into "Timestamp" and "Local time", can we change the specifications so that the display of "Timestamp" is the time on the Zabbix server side?
