60 x 60 = 3600 in 1 hour
3600 x 24 = 86400 in a day
8600 x 365 = 31,536,000 in a year
31536000 x 12 = 378,432,000 in 12 years
37869120 seconds approx. The exact number depends on how many leap years there were in the interval and on whether or not there were any leap seconds.
12 years is 378,683,112 seconds.
The International Astronomical Union definition of a second gives 31,557,600 seconds in a year. That makes 12 years = 378,691,200 seconds. And that is not counting the leap-second corrections that are made from time to time.
