suspend fun delay(timeMillis: Long): Unit (source)

Delays coroutine for a given time without blocking a thread and resumes it after a specified time. This suspending function is cancellable. If the Job of the current coroutine is cancelled or completed while this suspending function is waiting, this function immediately resumes with CancellationException.

Note that delay can be used in select invocation with onTimeout clause.

Implementation note: how exactly time is tracked is an implementation detail of CoroutineDispatcher in the context.


timeMillis - time in milliseconds.
