Sorry. Your variable is 32 bit. But if you write 60 * 60 * 24 ... etc. the compiler (may) think these are 16 bit and try to multiply them together and get an overflow. This is what the warning was about.
If you write (UInt32)60 * 60 * 24 ... you will force the compiler to use 32 bit for the first number, then it has to use 32 bit for the rest. However, it is much better to use predefined constants (even if the names are a bit confusing) since then you won't get the calculation wrong!
