-Regardless of the specifics of your trigger sync logic, to trigger sync your sensor needs to pass `true` to the [CreateShouldSyncReading function](https://pkg.go.dev/go.viam.com/rdk/services/datamanager#CreateShouldSyncReading) within the definition of your modular sensor's `Readings` function.

-The `sync-at-time` sensor does not sense time despite being named a time sensor.
-It _senses_ whether the data manager should sync or not and determines this based on the time of day.
-During the configured time of the day, the code will pass `true` to the [CreateShouldSyncReading function](https://pkg.go.dev/go.viam.com/rdk/services/datamanager#CreateShouldSyncReading) which will enable syncing:
+Regardless of the specifics of your trigger sync logic, to trigger sync your sensor needs to return a value for `should_sync` as part of your modular sensor's `Readings` function.
+The following example returns `"should_sync": true` if the current time is in a specified time window, and `"should_sync": false` otherwise.
