Description
The BSON_TYPE_TIMESTAMP type is not a date/time and is typically used for intra-server communication.
You probably want bson_iter_date_time().
The bson_iter_timestamp() function shall return the contents of a BSON_TYPE_TIMESTAMP element. It is invalid to call this function while observing an element that is not of type BSON_TYPE_TIMESTAMP.
