I have one more question on this if you don’t mind.  I’m a bit confused on how it works this way without it being in seconds?  I’ll answer below each step of how it seems to work to me.

So here it takes say 1000000 and divides it by 60 to put in seconds and spits out the remainder?  1000000 / 60 is approximately 16666 with a remainder of about 40, which would be the correct amount for seconds.  From there I get a little lost.

Then we take the remainder (40) from above and divide that by 60?  Already it’s confusing me.  

> minutes = time % 60
Are we still using the new number from above for time and dividing that by 60 and using the remainder for minutes?  

> time /= 60

Then taking the remainder from the line above and so on and so on…?

Also, would it work the same way with smaller divisors the other way around (from weeks - seconds)?
