Extra-biblical evidence of "Joshua's long day" and "Hezekiah’s sign"?

Joshua 10:12–14 describes that >the sun stood still in the midst of heaven, and hasted not to go down the space of one day. Victor Warkulwiz, *Universe without Space and Time* , ch. 2 claims >Joshua’s long day was observed around the world, as indicated in the folklore of various nations. With Hezekiah’s sign (Isaiah 38:7–8 , 4 Kgs 20:8-11 , 2 Par 32:24 ), the sun momentarily went backwards. What non-biblical historical evidence is there of "Joshua's long day" and "Hezekiah's sign"?
