SparkFun EL Sequencer delay timing issue.

I have a SparkFun EL Sequencer https://www.sparkfun.com/products/12781 when I tell it to:

delay(60000); 

it does way more 1 minute. I worked it out and the way it is now is 1 second = 485 milliseconds. so 1 minute = 29100 milliseconds.

I was able to program the unit using this conversion. But not sure why this is happening.

I modelled my code off of this.

Try two 30 second delays.

Why is that?
