[mpandya]

Description	This article describes why, after upgrading to v7.4.5, the GUI can be slow.
Scope	FortiGate.
Solution	After upgrading to v7.4.5, the GUI may experience a slowdown in the following tabs: Network. LDAP setting. Forward logs. FortiGuard setting. Local logs. Fabric management. To resolve the issue, go to System -> Settings -> System Time -> Time zone, check if zoneinfo/*/*  is mentioned, and replace it. From CLI : config system global     set timezone <integer> end To check which timezone corresponds to each integer value, after entering the 'set timezone' command in the CLI, press ?. This will display a full list of available timezones along with their assigned integer values. Example: If (GMT-12:00) zoneinfo/Etc/GMT+12 is mentioned, change it to (GMT-12:00) Etc/GMT+12. Do not use 'zoneinfo' in 'timezone'.
