This is an SAE Motor Vehicle Council draft document of the DSRC committee, subject to change.
<xs:minInclusive value="-127"/>
</xs:restriction>
</xs:simpleType>
Used By: This entry is used directly by one other data structure in this standard, a DF called
DF_VehicleStatus <ASN> <XML>. In addition, this item may be used by data structures in other ITS
standards.
7.38 Data Element: DE_DSecond
Use: The DSRC style second is a simple value consisting of integer values from zero to 61000
representing the milliseconds within a minute. A leap second is represented by the value range 60001 to
61000. The value of 65535 SHALL represent an unknown value in the range of the minute, other values
from 61001 to 65534 are reserved.
ASN.1 Representation:
DSecond ::= INTEGER (0..65535) -- units of miliseconds
XML Representation:
<xs:simpleType name="DSecond" >
<xs:annotation>
<xs:documentation>
units of miliseconds
</xs:documentation>
</xs:annotation>
<xs:restriction base="xs:unsignedShort"/>
</xs:simpleType>
Used By: This entry is directly used by the following 5 other data structures in this standard (record type,
descriptive name, ASN.1, and XML name (if present) of each):
DF
<XML>, and
DF
<XML>, and
DF
<XML>, and
MSG
<XML>, and
DF
In addition, this item may be used by data structures in other ITS standards.
Remarks: The need for a leap second arises from the difference between solar time and UTC time. Here
is a useful reference on this topic: http://en.wikipedia.org/wiki/Leap_second
7.39 Data Element: DE_DSignalSeconds
Use: The DSRC style of signal seconds is a simple value consisting of an integer value from zero to
30,000 representing a time value of from 0 to 300 seconds in 10 millisecond units from the moment the
message is issued.. The other values SHALL represent an unknown value, and are reserved at this time.
ASN.1 Representation:
DSignalSeconds ::= INTEGER (0..30000) -- units of 0.01 seconds
XML Representation:
<xs:simpleType name="DSignalSeconds" >
<xs:annotation>
<xs:documentation>
units of 0.01 seconds
