|arg||-||pointer to a std::time_t object to store the time, or a null pointer|
 Return value
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.
