时间戳转换C++代码实现
以下是将时间戳转换成RTC的C语言代码:
```c
#include <time.h>
#include <stdio.h>
#include <stdint.h>
typedef struct {
uint8_t second;
uint8_t minute;
uint8_t hour;
uint8_t day;
uint8_t month;
uint16_t year;
} rtc_t;
void timestamp_to_rtc(uint32_t timestamp, rtc_t *rtc) {
time_t time = (time_t) timestamp;
struct tm *tm_time = localtime(&time);
rtc->second = tm_time->tm_sec;
rtc->minute = tm_time->tm_min;
rtc->hour = tm_time->tm_hour;
rtc->day = tm_time->tm_mday;
rtc->month = tm_time->tm_mon + 1;
rtc->year = tm_time->tm_year + 1900;
}
int main() {
uint32_t timestamp = 1634380800; // 2021-10-16 00:00:00
rtc_t rtc;
timestamp_to_rtc(timestamp, &rtc);
printf("RTC time: %04d-%02d-%02d %02d:%02d:%02d\n",
rtc.year, rtc.month, rtc.day,
rtc.hour, rtc.minute, rtc.second);
return 0;
}
```
这个代码使用了time.h中的函数来将时间戳转换成本地时间,并将转换后的时间存储在一个自定义的rtc_t结构体中。然后,它可以输出RTC时间,也可以将这个结构体传递给其他函数以便进行其他操作。
