Description: ------------ In C++ : 1290594600000 % 86400000 = 37800000 //correct But In PHP : 1290594600000 % 86400000 = 30811200 //wrong However, in PHP : 1290594600000 - (floor(1290594600000/86400000)*86400000) = 37800000 //correct! Can modulo opertor be implemented this way when left value > PHP_INT_MAX ?
