Jasher 88:63 "And when they were smiting, the day was declining toward evening, and Joshua said in the sight of all the people, Sun stand thou still upon Gibeon, and thou moon in the valley of Ajalon, untill the nation have avenged itself upon its enemies.
88:64 And the sun stood still in the midst of the heavens, and it stood still six and thirty moments, and the moon also stood still and hastened not to go down a whole day. And there was no day like that before it or after it, that the lord hearkened to the voice of a man, for the Lord fought for Israel."

36 moments may be 36 hours; or 36 moments be 36 decans = 360° = a whole day 24 hours.

God may have moved the sun to the other side of the earth that day = 1.5 times around the earth = 36 hours, and earth flowed into a reverse orbit of the sun.

Or God may have moved the sun around the earth 360°, earth already in a reverse orbit of the sun, and earth continued in the reverse orbit to king Wan's dream.

"It is not surprising that this ancient document (Jasher) confirms the scripture and the chronology given in the Hebrew version of the Old Testament, once and for all settling the chronology differences between the Hebrew Old Testament and the Greek Septuagint."
Ancient Book of Jubilees. p.172.

Like the Ancient Book of Jubiless, exact ancient dates means the book of Jasher is authentic.

In the Dead Sea Scrolls there is space for two more verses after Joshua 10:11 = Joshua 10:12 and Joshua 10:13 that are in the book of Jasher.

The next line in the book of Jasher starts Chapter 89:1

Jasher 89:1 "Then spoke Joshua this song, on the day that the Lord had given the Amorites into the hand of Joshua and the children of Israel, and he said in the sight of all Israel,
89:2 Thou hast done mighty things, O Lord, thou hast performed great deeds; who is like unto thee? my lips shall sing to thy name.
89:3 My goodness, and my fortress, my high tower, I will sing a new song unto thee, with thanks, giving will I sing to thee. Thou art the strength of my salvation.
89:4 All the kings of the earth shall praise thee, the princes of the world shall sing to thee, the children of Israel shall rejoice in thy salvation, they shall sing and praise thy power.
89:5 To thee, O Lord, did we confide; we said thou art our God, for thou wast our shelter and strong tower against our enemies.
89:6 To thee we cried and were not ashamed, in thee we trusted and were delivered; when we cried unto thee, thou didst hear our voice, thou didst deliver our souls from the sword, thou didst show unto us thy grace, thou didst give unto us thy salvation, thou didst rejoice our hearts with thy strength.
88:7 Thou didst go forth with thy salvation, with thine arm thou didst redeem thy people; thou didst answer us from the heavens of thy holiness, thou didst save us from ten thousands of people.
88:8 The sun and moon stood still in heaven, and thou didst stand in thy wrath against our oppressors and did command thy judgements over them."
