(pañcadaśa-muhūrto divaso rātriś ca, 2.20.37) or other sources.
The expected third term, however, is found in Malayagiri's commentary on the Joisakarandaga:
tathā sūryadivasasyaikașasțir ghaţikāḥ parimāṇam, karmma-divasasasya şaşțir ghaţikāḥ, candra-divasasya... (p. 36). “The solar day measures 61 ghaţikās, the civil day
60,34 the lunar day ...".
Further, the JK defines time not only in time units but also in units of volume and units of weight. The reason is that the instrument used to measure time is a water clock, which discharges through a small hole certain amount of water in 24 minutes. The volume discharged in one nāļi is two ādhakas, and the weight of the water discharged in one nāļi is 100 palas.35 Malayagiri elaborates on this by systematically giving the volume and weight of each type of day:
ekaikasyām ca ghaţikāyām dvau dvāv ādhakāv iti divasasya meya-cintāyām: sūrya-divasasya dvāviņśam ādhaka-śatam parimāņam 122, karmma-divasasya viņšaty-uttaram ādhaka-satam 120 ... / ekaikasyām ca nālikāyām pala-satam iti tulyatva-cintāyām idam divasasya parimāņam: sūrya-divasasyaikașasțih palaśatāni parimāņam 6100, karmma-divasasya șașțih palaśatāni 6000 ... (M on JK p. 37). “In terms of the volume of the day, since in each ghaţikā (= nāļi) there are 2 ādhakas, the solar day has 122, the civil day 120 ... In terms of the weight of the day, since in one nālikā there are 100 palas, the size is as follows: the solar day has 6100, the civil day 6000...”.
