```c //************************************************ //EFI_TIME //************************************************ // This represents the current time information typedef struct { UINT16 Year; // 1900 - 9999 UINT8 Month; // 1 - 12 UINT8 Day; // 1 - 31 UINT8 Hour; // 0 - 23 UINT8 Minute; // 0 - 59 UINT8 Second; // 0 - 59 UINT8 Pad1; UINT32 Nanosecond; // 0 - 999,999,999 INT16 TimeZone; // —1440 to 1440 or 2047 UINT8 Daylight; UINT8 Pad2; } EFI_TIME; ```
