The basic unit of time is a nalika; defined as the time it takes for one adhaka
(1.87 kg or litres) of water to flow out of a pot through a hole of the same
diameter as that of a wire 4 angulas long made out of 4 mashas of gold. This
would be a hole approximately 0.6 mm diameter (23 or 24 gauge wire).
I. Subdivisions of the Nalika
                          tuta                         = 16/100ths of a second
      2 tutas             = 1 lava                     = 12/ 100ths of a second
      2 lavas             = 1 nimesha                  = 24/100ths of a second
      5 nimeshas          = 1 kashta                   = 1.2 seconds
      30 kashtas          = 1 kala                     = 36 seconds
      40 kalas            = 1 nalika                   = 24 minutes
      2 nalikas           = 1 muhurta                  = 48 minutes
      15 muhurtas         = a day or night             = 12 hours
II. Length of Days and Nights
Day and night of equal length (15 muhurtas each) occur in the month of
Chaitra (vernal equinox) and Asvayuja (autumnal equinox).
    The increase and decrease of daytime is as follows:
    1. From the vernal equinox daytime increases for 3 months to summer
         solstice (the longest day–18   muhurtas—14 hrs 24 minutes).
