Answer 1

下面是粘贴的哈，将就着看，time_t ---long tm是结构体。
typedef __kernel_time_t time_t;
typedef long __kernel_time_t;

struct tm {
164 /*
165 * the number of seconds after the minute, normally in the range
166 * 0 to 59, but can be up to 60 to allow for leap seconds
167 */
168 int tm_sec;
169 /* the number of minutes after the hour, in the range 0 to 59*/
170 int tm_min;
171 /* the number of hours past midnight, in the range 0 to 23 */
172 int tm_hour;
173 /* the day of the month, in the range 1 to 31 */
174 int tm_mday;
175 /* the number of months since January, in the range 0 to 11 */
176 int tm_mon;
177 /* the number of years since 1900 */
178 long tm_year;
179 /* the number of days since Sunday, in the range 0 to 6 */
180 int tm_wday;
181 /* the number of days since January 1, in the range 0 to 365 */
182 int tm_yday;
