From my checking, the retrieved TAKETM_MS values are not in order.
TAKETM_MS represents the time of the current Alert or Take message based on an
accurate GMT clock. It is not a timestamp of the retrieved messge.
According to the screentime, the TAKETM_MS (16:55:39.061) relates to the same headline.
This may indicate an update related to that headline.
