Notas
A codificação de tempo do calendário em std::time_t não é especificado, mas a maioria dos sistemas em conformidade com POSIX specification e retornar um valor de tipo integral mantendo o número de segundos desde a época. Implementações em que std::time_t é um 32-bit inteiros (muitas implementações históricos) falhar no ano de 2038.
Original:
The encoding of calendar time in std::time_t is unspecified, but most systems conform to POSIX specification and return a value of integral type holding the number of seconds since the Epoch. Implementations in which std::time_t is a 32-bit signed integer (many historical implementations) fail in the year 2038.
