Kilogram and three base units changed making all measures in base-units
It refers to National Physical Laboratory of India introducing from 20.05.2019 (World Metrology Day) the redefined International System of Units (SI units) for four base-units including Kilogram (Weight), Ampere (Electric Current), Kelvin (Temperature) and Mole (atoms) which will now onwards be based on constant of nature (quantum standards) rather than earlier being based on physical artefacts as per decision taken at General Conference of Weights and Measures at Versailles (France) in November 2018 meaning thereby that now onwards values of these units will never change. It is noteworthy that other three base units Second (Time), Metre (Length) and Candela (Luminous Intensity) are already based on constants of nature.
But India should take lead in taking up matter of metric-measure of base-unit of time with General Conference of Weights and Measures. Metric unit of time should be introduced with a complete day divided in 10 metric hours instead of present 24 hours. Each metric hour may have 100 metric minutes with a metric minute having 100 metric seconds thereby making a complete day of 100000 metric seconds instead of present 86400 seconds.
India should also advance its time-zone by half an hour to make it GMT+6 hours rather than present haphazard GMT+5.30 hours as also recommended by National Institute of Advanced Studies. Since presently just eight countries in the world deviate from separating their time-zones by fraction of an hour, Indian government should approach international authorities so that time-zone for a country may compulsorily be deviated by full one hour from GMT.
Making Indian Time at GMT+6 hours will fulfil long-pending and genuine demand of people from north-east India without going for dual and impractical time-zone for the country. Change will reduce big time-difference of 127 minutes between extreme east and west zones of the country. Demand of north-eastern states is highly justified for better utilisation of day-time energy when sun-rise and sun-set are comparatively much earlier there than rest of the country.
