Table 6.235—DRM_Relative_Time_Interval

Property

Description

Superclass

· <DRM Time Interval>

Class

· <DRM Relative Time Interval>

Subclass

· none

Definition

An object of this DRM class specifies an interval of time, defined by a start time and a stop time that are relative to another time.

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".

Notes

¹ Used to indicate the significance of the time information.

² If present, the <DRM Time Interval> is relative to an absolute time. Otherwise, the <DRM Time Interval> is relative to simulation start.
