That's how the C Standard says things are supposed to work.  The type of the 
result of the multiplication operator is determined solely by the types of the 
two operands.  The fact that the result will then be assigned to a u64 object 
has no effect on the initial result of the multiplication.

I suggest something like

u64 const dce_ticks_per_second =10000000;
u64 dce_time = unix_time_which_is_u32 * dce_ticks_per_second;
