The time duration needed for the integration of three trasarenus is called a truti, and one hundred trutis make one vedha. Three vedhas make one lava.
It is calculated that if a second is divided into 1687.5 parts, each part is the duration of a truti, which is the time occupied in the integration of eighteen atomic particles. Such a combination of atoms into different bodies creates the calculation of material time. The sun is the central point for calculating all different durations.
