2.8.25 TimeNodeTimeFilter
Referenced by: TimeVariant4TimeNode
An atom record that specifies a time filter that transforms a given time to the local time of a time node.
Let the corresponding time node be as specified in the TimePropertyList4TimeNodeContainer record (section 2.8.18) that contains this TimeNodeTimeFilter record.

rh (8 bytes): A RecordHeader structure (section 2.3.1) that specifies the header for this record. Sub-fields are further specified in the following table.
-
Field
Meaning
rh.recVer
MUST be 0x0.
rh.recType
MUST be an RT_TimeVariant.
rh.recLen
MUST be an odd number.
type (1 byte): A TimeVariantTypeEnum enumeration that specifies the data type of this record. It MUST be TL_TVT_String.
timeFilter (variable): A UnicodeString that specifies the time filter that transforms a given time value into the local time of the corresponding time node. It MUST be a valid TIMESEQUENCE as specified in the following ABNF (specified in [RFC5234]) grammar:
-
TIMESEQUENCE = TIME "," TRANSTIME *(";" TIMESEQUENCE) TIME = "0" "." 1*DIGIT / "1" "." "0" TRANSTIME = "0" "." 1*DIGIT / "1" "." "0" -
Each TIME is the normalized local time for the time node whose value ranges from 0.0 to 1.0, and TRANSTIME is the transformed local time for the time node. The length, in bytes, of the field is specified by the following formula:
-
rh.recLen - 1
