getlocaltime里面是没有时区信息的。你可以这样:time_t time_utc = 0;struct tm *p_tm_time;int time_zone = 0;p_tm_time = localtime( &time_utc ); //转成当地时间time_zone = ( p_tm_time->tm_hour > 12 ) ? ( p_tm_time->tm_hour-= 24 ) : p_tm_time->...
14:_get_timezone() 协调世界时 (UTC) 和当地时间之间的差异(以秒为单位)。 longzone; _get_timezone(&zone); 15:_get_daylight(int* hours ) 夏令时偏移量小时 inthours; _get_daylight(&hours); 16 :_get_dstbias(int* seconds );夏令时偏移量秒...
使用C语言编写程序需要获得当前精确时间(1970年1月1日到现在的时间),或者为执行计时,可以使用gettimeofday()函数。用 法: void gettime(struct time *timep);C语言函数 include <sys/time.h> int gettimeofday(struct timeval*tv, struct timezone *tz);其参数tv是保存获取时间结果的结构体,参...
C 时区timezone voidtest_time(){time_t time_utc;structtmtm_local;// Get the UTC timetime(&time_utc);// Get the local time// Use localtime_r for threads safelocaltime_r(&time_utc,&tm_local);time_t time_local;structtmtm_gmt;// Change tm to time_ttime_local=mktime(&tm_local);/...
GetLocalTime 获得系统本地时间 --- 例子 #include <windows.h>#include<stdio.h>voidmain() { SYSTEMTIME st, lt; GetSystemTime(&st); GetLocalTime(<); printf("The system time is: %02d:%02d\n", st.wHour, st.wMinute); printf("The local time is: %02d:%02d\n", lt.wHour, lt.wMinute)...
