Technical Tip: FortiGate local certificate generated from FortiManager is backdated by seven days
| Description | This article explains how, when generating a local certificate for the FortiGate device from FortiManager, the certificate's validity will begin seven days prior to the current date. |
| Scope | FortiManager. |
| Solution | For example, create a new local certificate on FortiManager to be used on FortiGate(s).
Generate the certificate:
 Install it on the device(s):
Check the installed local certificate on FortiGate and the certificate is valid starting from 2025/07/07, whereas FortiManager's system time is 2025/07/14, which is seven days ahead of the certificate’s start date.
