Method getDeviceAndHostTimer

include/CL/opencl.hpp:2484–2496

* Return a synchronized pair of host and device timestamps as seen by device. * Use to correlate the clocks and get the host timer only using getHostTimer * as a lower cost mechanism in between calls. * The resolution of the host timer may be queried with the * CL_PLATFORM_HOST_TIMER_RESOLUTION query. * The resolution of the device timer may be queried with the * CL_

     * @return A pair of (device timer, host timer) timer values.
