This is an SAE Motor Vehicle Council draft document of the DSRC committee, subject to change.
Used by: This entry is directly used by the following 2 other data structures in this standard (record type, descriptive name,
ASN.1, and XML name (if present) of each):
DF
DF
In addition, this item may be used by data structures in other ITS standards.
6.6 Data Frame: DF_DDate
Use: The DSRC style date is a compound value consisting of finite-length sequences of integers (not characters) of
the form: "yyyy, mm, dd" - as defined below. Because the length of each element is known, no inner element
tagging is normally used in transmission. Thus, this data frame occupies 4 bytes in total.
ASN.1 Representation:
DDate ::= SEQUENCE {
year DYear, -- 2 bytes
month DMonth, -- 1 byte
day DDay -- 1 byte
}
XML Representation:
<xs:complexType name="DDate" >
<xs:sequence>
<xs:element name="year" type="DYear" />
<!-- 2 bytes -->
<xs:element name="month" type="DMonth" />
<!-- 1 byte -->
<xs:element name="day" type="DDay" />
<!-- 1 byte -->
</xs:sequence>
</xs:complexType>
Used by: This entry is used directly by one other data structure in this standard, a DF called DF_ValueList <ASN>
<XML>. In addition, this item may be used by data structures in other ITS standards.
6.7 Data Frame: DF_DDateTime
Use: The DSRC style date is a compound value consisting of finite-length sequences of integers (not characters) of
the form: "yyyy, mm, dd, hh, mm, ss (sss+)" - as defined below. Because the length of each element is known,
no inner element tagging is normally used in transmission. Thus, this data frame occupies 8 bytes in total.
ASN.1 Representation:
DDateTime ::= SEQUENCE {
year DYear, -- 2 bytes
month DMonth, -- 1 byte
day DDay, -- 1 byte
hour DHour, -- 1 byte
minute DMinute, -- 1 byte
}
XML Representation:
<xs:complexType name="DDateTime" >
<xs:sequence>
<xs:element name="year" type="DYear" />
<!-- 2 bytes -->
<xs:element name="month" type="DMonth" />
<!-- 1 byte -->
<xs:element name="day" type="DDay" />
<!-- 1 byte -->
<xs:element name="hour" type="DHour" />
<!-- 1 byte -->
