Fortigate - How do I find date when IP assigned to interface changed?

[PIOJ_Tech_Support]

Good day all. The IP address assigned to one of my WAN interfaces on my Fortigate changed unexpectedly a few days ago. It is assigned by my ISP via DHCP. Is there a log I can check to determine exactly when this happened?
