Clarifications

¹ This indicates the significance of the time information.

² If the given <DRM Relative Time Interval> instance R has an <DRM Absolute Time> component, R is relative to the specified absolute time; otherwise, R is relative to “simulation start” - that is, the start time of the consuming application.

Example(s)

The time period for which a SEDRIS transmittal should be considered to be valid. The stop time can be considered to be an “expiration date”.
