The Timestamp property returns the local date and time the
most recent response was received from the provider. The value is
formatted using the current user's regional date and time settings.
This property is updated after a successful call to the
Ask or SendMessage method. If no response has been
received, this property will return an empty string.
The timestamp represents when the response was received by the
control, not necessarily when the response was generated by the
provider. Some providers may also include their own internal
timestamps as part of the response metadata, but those values are not
returned by this property.
Because the value returned by this property is formatted using the
current user's locale settings, the exact format of the date and time
string may vary between systems. Applications that require
locale-independent date and time handling should store or convert the
value using an appropriate date and time format.
This property only reflects the timestamp associated with the most
recent response. Applications can retrieve timestamp values for
messages stored in the conversation history by using the
GetFirstMessage, GetNextMessage or GetMessage
methods.
