to break it down for a better understanding of how i got my answer....
60 seconds = 1min
60 minutes = 1 hour
24 hours = 1 day
365 days = 1 year
60 secs * 60 mins = 3600 seconds in an hour
3600 seconds per hour = 86,400 seconds per day (24 hours)
86,400 seconds a day * 365 days (a year) = 31,536,000
x 2 (years)
___________
~ 63,072,000 secs for 2 years
