Identifies whether an interval of a particular duration (resp. starting at a particular time) is indeed an interval of the mentioned duration plus or minus some number of milliseconds, seconds and minutes (resp. an interval starting at the mentioned time plus or minus some number of milliseconds, seconds and minutes.
A set of points originating from the same realm are reasonably synchronized. Within a realm, one can assume that time-stamped objects sorted by time are in the order of their occurrence. Between realms, this assumption is rebuttable. A system border is crossed in an interaction when the 2 communication partners are not synchronized based on the same time source.
Indicates that the time source of the sending device support leap seconds adjustments.
Indicates that the time source of the sending device is not synchronized with the external UTC time source. The timestamp should be ignored except for sequencing.
Indicates that the time source of the sending device is unreliable. The timestamp should be ignored.
Represents the time accuracy class of the time source of the sending device relative to the external UTC time source.
