二十念名一瞬顷。二十瞬名一弹指。二十弹指名一罗豫。二十罗豫名一须臾。日极长时有十八须臾。夜极短时有十二须臾夜极长时有十八须臾。日极短时有十二须臾。
— 卷十七,《摩诃僧祗律》

During the Jin dynasty (266-420), a record of Mahasangha Vinaya (Sanksrit buddhist scriptures) translated by Buddabhadra and Chinese monk Faxian revealed one of the earliest intuition and understanding of the concept and value of time.

Literal translation from Volume 17, Mahasangha Vinaya: “20 thoughts make a blink moment. 20 blink moments is a snap of a finger. 20 snaps of a finger make as an anticipation. 20 anticipations is a moment. a long day is 18 moments. a short night is 12 moments, and a long night is 18 moments. a short day is 12 moments.”
