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!)
