ObserveEventImpossible(ulSessionID,uSequenceID,sIntegrity,sEventID,sEventParameterValue,sTime)

Observe that this event has become impossible. Events can change from possibilities to impossibilities through observation. Optionally specifying the observed value and the time it occurred - consequently making this event impossible. This unofficial observation enables reputable observers to provide an informative service until such time as official observers can establish the official historical record. A contingency cannot be determined until all the events it depends upon have been officially determined.

PARAMETERS

ulong ulSessionID 

ID of authenticated session.

uint uSequenceID 

Sequence number.

string sIntegrity 

md5("ipaddr(sid,seq)->ObserveEventImpossible(sEventID,sEventParameterValue,sTime)/secret")

string sEventID 

Unique ID of parent event. Cannot specify root (official history).

string sEventParameterValue 

The value the event parameter is observed to have (blank if unknown).

string sTime 

Time at which event became impossible and if known, the observed value occurred (leave blank for current time).

RETURNS

SEventRecordData {sEventID,sParameterValue,sParameterType,sAgentIDObserver,bOccurred,sTimeOccurred,sTimeObserved}

string sEventID 

ID of event observed to occur.

string sParameterValue 

The value the event parameter is observed to have (blank if unknown).

string sParameterType 

Type of the parameter.

string sAgentIDObserver 

Empty if official, otherwise ID of most recent observer.

bool bOccurred 

True if this is a record of the event occurring, False if a record of the event becoming impossible.

string sTimeOccurred 

Time at which the event occurred/or not.

string sTimeObserved 

Time this event record was originally submitted - Blank for official observations.

FAULTS

Session. Event. Time format.
