SB 8.24.37

aham tvam rsibhih sardham
 saha-navam udanvati
vikarsan vicarisyami
 yavad brahmi nisa prabho
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Pulling the boat, with you and all the rsis in it, O King, I shall travel in the water of devastation until the night of Lord Brahma’s slumber is over.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
This particular devastation actually took place not during the night of Lord Brahma but during his day, for it was during the time of Caksusa Manu. Brahma’s night takes place when Brahma goes to sleep, but in the daytime there are fourteen Manus, one of whom is Caksusa Manu. Therefore, Srila Visvanatha Cakravarti Thakura comments that although it was daytime for Lord Brahma, Brahma felt sleepy for a short time by the supreme will of the Lord. This short period is regarded as Lord Brahma’s night. This has been elaborately discussed by Srila Rupa Gosvami in his Laghu-bhagavatamrta. The following is a summary of his analysis. Because Agastya Muni cursed Svayambhuva Manu, during the time of Svayambhuva Manu a devastation took place. This devastation is mentioned in the Matsya Purana. During the time of Caksusa Manu, by the supreme will of the Lord, there was suddenly another pralaya, or devastation. This is mentioned by Markandeya Rsi in the Visnu-dharmottara. At the end of Manu’s time there is not necessarily a devastation, but at the end of the Caksusa-manvantara, the Supreme Personality of Godhead, by His illusory energy, wanted to show Satyavrata the effects of devastation. Srila Sridhara Svami also agrees with this opinion. The Laghu-bhagavatamrta says:
 
madhye manvantarasyaiva
 muneh sapan manum prati
pralayo ’sau babhuveti
 purane kvacid iryate
 
ayam akasmiko jatas
 caksusasyantare manoh
pralayah padmanabhasya
 lilayeti ca kutracit
 
sarva-manvantarasyante
 pralayo niscitam bhavet
visnu-dharmottare tv etat
 markandeyena bhasitam
 
manor ante layo nasti
 manave ’darsi mayaya
visnuneti bruvanais tu
 svamibhir naisa manyate
