驱动中打印系统时间

编程入门行业动态更新时间:2024-10-27 12:35:27

在驱动中打印本地时间三个步骤：
1、在驱动中调用KeQuerySystemTime获取GMT系统时间
2、调用ExSystemTimeToLocalTime将GMT系统时间转换为本地系统时间
3、调用RtlTimeToTimeFields将本地时间转换为TIME_FIELDS结构体
TIME_FIELDS结构体定义如下：
typedef struct _TIME_FIELDS {
CSHORT Year; // range [1601...]
CSHORT Month; // range [1..12]
CSHORT Day; // range [1..31]
CSHORT Hour; // range [0..23]
CSHORT Minute; // range [0..59]
CSHORT Second; // range [0..59]
CSHORT Milliseconds;// range [0..999]
CSHORT Weekday; // range [0..6] == [Sunday..Saturday]
} TIME_FIELDS;
typedef TIME_FIELDS *PTIME_FIELDS;
实现如下：
CHAR szTime[128];
LARGE_INTEGER systemTime, localTime;
TIME_FIELDS timeField;
KeQuerySystemTime(&systemTime)；
ExSystemTimeToLocalTime（&systemTime, &localTime);
RtlTimeToTimeFields（&localTime, &timeField);
sprintf("%d-%02d-%02d %02d:%02d:%02d:%03d",timeField.Year, timeField.Month, timeField.Day, timeField.Hour, timeField.Minute, timeField.Second, timeField.Milliseconds)
