Class MessageCreationTime

org.jmisb.api.klv.st0603.ST0603TimeStamp

org.jmisb.api.klv.st0808.MessageCreationTime

All Implemented Interfaces:

IKlvValue, IAncillaryTextMetadataValue

public class MessageCreationTime
extends ST0603TimeStamp
implements IAncillaryTextMetadataValue

Message Creation Time (ST0808 Ancillary Text Local Set Tag 5).

The Message Creation Time element identifies the time at which the ancillary text message was created (e.g. if added to the stream during analysis subsequent to the initial recording).

This element is encoded in the same manner as the Precision Time Stamp defined in MISB ST 0603. Whereas the mandatory PrecisionTimeStamp marks wherein the Motion Imagery stream the message applies, the Message Creation Time marks when the message is generated. For example, if a message applies to Motion Imagery with frame time X, but is being created at a later time, such as in a latter phase of exploitation, the message would have a Message Creation Time of Y. In the case where the message is made in real time with respect to the Motion Imagery, then the times X and Y would be the same.

The Precision Time Stamp is an optional element in the ancillary text metadata set.

Resolution is 1 microsecond.
