Webfunction time time_t time (time_t* timer); Get current time Get the current calendar time as a value of type time_t. The function returns this value, and if the argument is not a null pointer, it also sets this value to the object pointed by timer. WebThe current implementation of system_clock is related an epoch (midnight UTC of January 1, 1970), but this is not in the contract. You need to use the static function static. std::time_t to_time_t(const time_point& t); which returns a time_t type that is based on midnight UTC of January 1, 1970.
