+## Controlling Expiration Timing
+
+Expiration is computed from a [`TimeProvider`](https://learn.microsoft.com/dotnet/api/system.timeprovider),
+defaulting to `TimeProvider.System`. Register a `TimeProvider` in DI to override the clock the cache uses —
+for example, to drive expiration deterministically in tests with
+[`FakeTimeProvider`](https://learn.microsoft.com/dotnet/api/microsoft.extensions.time.testing.faketimeprovider):
+
+```csharp
+services.AddSingleton<TimeProvider>(new FakeTimeProvider());
+services.AddNatsDistributedCache(options => options.BucketName = "cache");
+```
+
