Description

This article describes the issue that timestamps shown by Packet Capture are incorrect.

Scope Before FortiGate 7.2.8 version.
Solution

The Packet Capture timeline graph does not accurately display the traffic, especially when capturing too much inbound traffic at Network -> Diagnostics -> Packet Capture.

The timeline graph feature in Packet Capture was removed starting with FortiGate v7.2.9. While the previous method for measuring packet capture time provided a reasonable estimate of traffic, it became less accurate with high traffic volumes and could potentially mislead users.
