# core/perf/timer/engines This module contains the engines that send time metrics to a target destination. ## Overview Each engine has to implement the `PerfTimerEngine` interface. It means that an engine should have the following methods: * `sendDelta` - to send metrics data * `getTimestampFromTimeOrigin` - returns a timestamp from the application start. In the simple example, it could be `performance.now()`, but the engine can define the precision and the moment the application starts.
