Was the Divine Mercy Revelation a Harbinger of the End Times?

Write down these words, my daughter. Speak to the world about My mercy; let all mankind recognize My unfathomable mercy. It is a sign for the end times; after it will come the day of justice. While there is still time let them have recourse to the fount of My mercy (Diary 429).

You have to speak to the world about His great mercy and prepare the world for the Second Coming of Him who will come, not as a merciful Savior, but as a just Judge. Oh how terrible is that day! Determined is the day of justice, the day of divine wrath. The angels tremble before it. Speak to souls about this great mercy while it is still the time for granting mercy (Diary 635).

Tell souls about this great mercy of Mine, because the awful day, the day of My justice, is near (Diary 965).

Write this: before I come as the Just Judge, I am coming first as the King of Mercy. Before the day of justice arrives, there will be given to people a sign in the heavens of this sort: All light in the heavens will be extinguished, and there will be great darkness over the whole earth. Then the sign of the cross will be seen in the sky, and from the openings where the hands and the feet of the Savior were nailed will come forth great lights which will light up the earth for a period of time. This will take place shortly before the last day. (Diary 83).
