MTDriver_CheckTime得出来的时间戳不准确

在XP和win7下测试，得出来的时间戳都不准确，比正确时间戳晚了很多。以下为修正后代码：
`#include <ntddk.h>

const unsigned char g_day_per_mon[12] = { 31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31 };

/*

• 功能：

• 判断是否是闰年
  

• 参数：

• year：需要判断的年份数
  

• 返回值：

• 闰年返回1，否则返回0
  

*/
unsigned char applib_dt_is_leap_year(unsigned short year)
{
if ((year % 400) == 0) {
return 1;
} else if ((year % 100) == 0) {
return 0;
} else if ((year % 4) == 0) {
return 1;
} else {
return 0;
}
}

/*

• 功能：

• 得到每个月有多少天
  

• 参数：

• month：需要得到天数的月份数
  

• year：该月所对应的年份数
  

• 返回值：

• 该月有多少天
  

*/
unsigned char applib_dt_last_day_of_mon(unsigned char month, unsigned short year)
{
if ((month == 0) || (month > 12)) {
return g_day_per_mon[1] + applib_dt_is_leap_year(year);
}

if (month != 2) {
    return g_day_per_mon[month - 1];
} else {
    return g_day_per_mon[1] + applib_dt_is_leap_year(year);
}

}

    no_of_days += applib_dt_last_day_of_mon((unsigned char) i, iYear);
}

/* sec */

Windows on ARM, Support?

Please let us know when can we have an ARM64 version for Windows on ARM OS. We can help you test We have Windows on Rasberry Pi setup. Please pursue it we at Windows on Rasberry Pi community will be glad to extend support in testing your drivers and tools for ARM64.
