- 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)
