Viren,
I just went through the first link about dating of Chandragupta II. Dr. A. Sharan is a supporter of the 'text-book' history of Gupta-era, whereas in contrast Dr. Sethna is the leading light of a new school which wants to see the available facts in a radically new light and has successfully argued against many of the standard historical beliefs we have been taught to have been actually false. For example Dr. Sethna shows that chANakya-maurya empire must have existed BEFORE the invasion of Alexander. Or for example, the possibility of multiple Ashoka-s in the mauryan dynasty alone, or the pillars-edicts of the great Ashoka to have been from several different "Ashoka" kings calling themselves by different names as well - devapiya, piyadassI etc, on different occasions... All these theories are still in infancy but do have a solid potential of forcing us to shift back the dating of historical events the way we have been taught all the while (and supported by Dr. Sharan).
