Described are examples for synchronizing multiple timing sources in a computing device. At least a first clock associated with a first timing source and a second clock associated with a second timing source can be maintained at the computing device. A request for an indication of a difference in values between the first clock and the second clock can be received from the application. A first elapsed time of the first clock and a second elapsed time of the second clock from a previous instance of an event can be determined by the computing device at an instance of a reoccurring event in a domain of one of the first timing source or the second timing source. An indication related to the first elapsed time and the second elapsed time can be provided to the application.
