Linux C/C++时间字符串与time_t之间的转换方法(转)

1.指定time_t类型的时间，格式化为YYYYMMDDHH24MISS型的字符串

void FormatTime(time_t time1, char *szTime)

{

       struct tm tm1;

#ifdef WIN32

       tm1 =*localtime(&time1);

#else

      localtime_r(&time1,&tm1 );

#endif

       sprintf( szTime,"%4.4d%2.2d%2.2d%2.2d%2.2d%2.2d",

                  tm1.tm_year+1900,tm1.tm_mon+1, tm1.tm_mday,

                     tm1.tm_hour, tm1.tm_min,tm1.tm_sec);

}

 

2.指定YYYYMMDDHH24MISS型的时间，格式化为time_t型的时间

time_t FormatTime2(char * szTime)

{

       struct tm tm1;

       time_t time1;

       sscanf(szTime, "M-----",   

                 &tm1.tm_year,

                 &tm1.tm_mon,

                 &tm1.tm_mday,

                 &tm1.tm_hour,

                 &tm1.tm_min,

                 &tm1.tm_sec);

            

       tm1.tm_year -= 1900;

       tm1.tm_mon --;

       tm1.tm_isdst=-1;

   

       time1 =mktime(&tm1);

       return time1;

}
