This year minus 31 years 7 months (approx).
One billion seconds ago is roughly the equivalent of 31.7 years ago, using the US definition of one billion. One billion is one thousand millions.
One billion seconds equals about 31.68 years. 31.68 years ago in 1978, Jimmy Carter was president.
A.A billion seconds ago it was 1959.B.A billion minutes ago Jesus was alive.C.A billion hours ago our ancestors wereliving in the Stone Age.D.A billion days ago no-one walked on the earth on two feet.
1 billion minutes ago was the year 110 . 1 billion minutes later will be the year 3913 .
1 trillion seconds is equivalent to about 31,688 years ago. So, subtracting that from the current year would give the approximate year.
That was about 114,155 years ago, or 112,142 BC
Using the calculated year of 365.25 days, which is 31,557,600 seconds per year,30000 years would be 946,728,000,000 seconds (946.728 billion, US)Using the SI year, which is 31,556,926 seconds,30000 years would be 946,707,780,000 seconds (946.708 billion, US).

1 year is approximately 31.56 million seconds, so 60 billion seconds is a little over 1901 years.
There are 60 seconds in a minute and sixty minutes in an hour, so each hour is 3600 seconds. Multiply 24 to get days, and then 365.25 to get years, accounting for leap years. This is 31,557,600 seconds per year. Divide 1,000,000,000 seconds by 31,557,600 seconds per year, and you get 31 years, 251 days, 7 hours, 46 minutes and 40 seconds. (Why didn't I figure out the months? Because the months aren't equal!)
It is currently 2008...Since there was no Year Zero, it was 999997993 B.C. one billion years ago. Or, if you prefer the Long Scale (non-American) definition of a billion, it was 999999997993 B.C.
