If your Identity Provider's clock is not synchronized, the validation of the token could fail.
+If the deviation is only some seconds, you can use the AuthConfig.clockSkewInSec setting to allow a bigger time window deviation.
However, you may need to adjust the base time, that is used for the token validation and make sure, that the AuthConfig.clockSkewInSec is still a small reasonable number, then you can implement a custom DateTimeProvider.
To do so, create a new service that derives from DateTimeProvider:
export class MyCustomDateTimeProvider extends DateTimeProvider {
+ now(): number {
+ // Return your custom now.
+ return Date.now();
+ }
+
+ new(): Date {
+ // Return your custom new Date().
+ return new Date();
+ }
+}Then, override the provider via dependency injection in your application:
+@NgModule({
+ imports: [
+ // etc.
+ OAuthModule.forRoot()
+ ],
+ providers: [
+ { provide: DateTimeProvider, useClass: MyCustomDateTimeProvider } // <- add this
+ ],
+ declarations: [
+ AppComponent,
+ // etc.
+ ],
+ bootstrap: [
+ AppComponent
+ ]
+})
+export class AppModule {
