Techniques are provided for managing Presentation Time in a digital rendering system for presentation of temporally-ordered data when the digital rendering system includes a Variable Rate Presentation capability. In one embodiment, Presentation Time is converted to Data Time, and Data Time is reported instead of Presentation Time when only one time can be reported. In another embodiment, a predetermined one of Presentation Time and Data Time is returned in response to a request for a Current Time.
