Beacuse of a DAM made in China the time of the 1 day of our earth is carried out by - 40 mini seconds means now

1 day = 23 hours 57 minutes 59 seconds and 60 mini seconds

Answer 2

Answer:

1 day is not exactly 24 hours it's only for uniform distribution of time all along 365 days it's 23 hours 59 minutes and 59 seconds

Explanation:

Every four years we add up the 4 hours extra because one year is of 365 days and 6 hours

so 6*4= 24 hours so we have an extra day that year i.e. the leap year or 29th February
