请问一下 struct tm的用法，如何实现动态符值啊，

[nw1982]

各位大哥，在VC中，struct tm具体是怎么用的，怎么任意符值呢，谢谢！

[独孤过儿]

猜谜？

[vecshid]

tm不就是时间的结构体吗？里面存有一些例如秒、分、时等时间信息~

任意符值？？？？？

我机器上的

struct tm
{
  int tm_sec;                   /* Seconds.     [0-60] (1 leap second) */
  int tm_min;                   /* Minutes.     [0-59] */
  int tm_hour;                  /* Hours.       [0-23] */
  int tm_mday;                  /* Day.         [1-31] */
  int tm_mon;                   /* Month.       [0-11] */
  int tm_year;                  /* Year - 1900.  */
  int tm_wday;                  /* Day of week. [0-6] */
  int tm_yday;                  /* Days in year.[0-365] */
  int tm_isdst;                 /* DST.         [-1/0/1]*/

#ifdef  __USE_BSD
  long int tm_gmtoff;           /* Seconds east of UTC.  */
  __const char *tm_zone;        /* Timezone abbreviation.  */
#else
  long int __tm_gmtoff;         /* Seconds east of UTC.  */
  __const char *__tm_zone;      /* Timezone abbreviation.  */
#endif
};

VC8版的

struct tm {
        int tm_sec;     /* seconds after the minute - [0,59] */
        int tm_min;     /* minutes after the hour - [0,59] */
        int tm_hour;    /* hours since midnight - [0,23] */
        int tm_mday;    /* day of the month - [1,31] */
        int tm_mon;     /* months since January - [0,11] */
        int tm_year;    /* years since 1900 */
        int tm_wday;    /* days since Sunday - [0,6] */
        int tm_yday;    /* days since January 1 - [0,365] */
        int tm_isdst;   /* daylight savings time flag */
        };
