最近因工作需要把单片机的YYMMDDHHMMSS转为Unix的时间戳，网上大多都是上位机的程序，经过搜索引擎的帮助下，终于实现了把单片机的时间转为Unix的时间戳，特贴出代码给社区内需要的朋友，转载请注明出处！！！: Y" o: S9 Q1 i/ `
9 s5 ^6 _( @- z& z$ M$ I1 M" M由于使用了 struct tm 结构体好是mktime，所以需要包含 <time.h>头文件，把下面的年月日时分秒换成实际的年月日时分秒即可! f% u: }# W* @. g

实测没毛病，这是HAL库，不懂别乱说
要是把时间戳转本地时间的函数也写出来就更好了。5 M8 {1 U/ K: q3 ^2 b f: [. u
typedef unsigned int time_t; / date/time in unix secs past 1-Jan-70 /
extern _ARMABI time_t mktime(struct tm /timeptr*/) attribute((nonnull(1)));
//本地时间生成时间戳函数 uint32_t TimeToTimeStamp(void) { struct tm stm; memset(&stm,0,sizeof(stm)); stm.tm_year = TimeData.year - 1900; //RTC_Year rang 0-9999,but tm_year since 1900 stm.tm_mon = TimeData.month - 1; //RTC_Month rang 1-12,but tm_mon rang 0-11 stm.tm_mday = TimeData.day; //RTC_Date rang 1-31 and tm_mday rang 1-31 stm.tm_hour = TimeData.hour - 8; //RTC_Hours rang 0-23 and tm_hour rang 0-23 stm.tm_min = TimeData.minute; //RTC_Minutes rang 0-59 and tm_min rang 0-59 stm.tm_sec = TimeData.second; return mktime(&stm); }
