WINDOWS api--getfiletime--Get file time

The FILETIME structure contains the date and time information for the file or directory: (since January 1, 1601, the unit is 100 nanoseconds)

struct _filetime {  // Low 32-bit    // High 32-bit  *pfiletime;

The SYSTEMTIME structure contains user-identifiable system date information:

typedefstruct_systemtime {WORD wyear;//yearsWORD wmonth;//MonthWORD Wdayofweek;//the day of the weekWORD wday;//DayWORD Whour;//hoursWORD Wminute;//pointsWORD Wsecond;//secondsWORD wmilliseconds;//milliseconds} SYSTEMTIME,*psystemtime;

=======================================================

The function filetimetosystemtime is used to convert the file time format to the standard system time format:

BOOL WINAPI filetimetosystemtime (  __in   const// file time   __out   // System Time );

The function filetimetolocaltime is used to convert the file time format to a local file time:

BOOL WINAPI filetimetolocalfiletime (  __in          const filetime* lpfiletime,// file Time   __out         lpfiletime lplocalfiletime// Local file time );

The function systemtimetofiletime is the conversion of standard system time into a file time format:

BOOL WINAPI systemtimetofiletime (   __in   const SYSTEMTIME *lpsystemtime,//  System time   __out  lpfiletime lpfiletime// file time );

The function systemtimetotzspecificlocaltime is to convert the standard system time to the local system time

BOOL WINAPI systemtimetotzspecificlocaltime (__in          lptime_zone_information lptimezone,// time zone structure __in          lpsystemtime lpuniversaltime,// system time __out         lpsystemtime Lplocaltime// local time );

=======================================================

The GetSystemTime function is used to obtain the system time:

void WINAPI getsystemtime (   __out  lpsystemtime lpsystemtime);

The getfiletime function is used to obtain the time of creation of a file or directory, the last access time, and the last modified time:

BOOL WINAPI getfiletime (  __in       // file or directory handle  __out_opt  // returns the date and time information  that was created __out_opt  // returns the last accessed date and time information  __out_opt  // returns the last modified date and time information );

Instance:

CString strpath ("D:\\test.txt"); HANDLE hfile=CreateFile (strpath, Generic_write| Generic_read,//must have Generic_read attribute to get timeFile_share_read, NULL,                          Truncate_existing, File_attribute_normal,                 NULL); if(hfile! =Invalid_handle_value)    {SYSTEMTIME sysTime; GetSystemTime (&systime);//the time we get here is the standard system time, which is 0 time zone. Getlocaltime (&systime);//this gets the local time, which is the standard Time + time zone.FILETIME fcreatetime, Faccesstime, Fwritetime; Getfiletime (&hfile, &fcreatetime, &faccesstime, &fwritetime);//Get file TimeCString strtime;//two ways to convert the file time to the local system time://(1)FileTimeToLocalFileTime (&fcreatetime,&localtime);//convert file time to local file timeFileTimeToSystemTime (&localtime, &systime);//convert file time to Local system time//(2)FileTimeToSystemTime (&fcreatetime, &systime);//convert file time to standard system timeSystemtimetotzspecificlocaltime (&systime, &systime)//Convert standard system time to local system timeStrtime.format (_t ("%4d year%2d month%2d day,%2d:%2d:%2d"), Systime.wyear, Systime.wmonth, Systime.wday, Systime.whour, Systime.wminute, Systime.wsecond);}

Repair file creation time, example:

#include <Windows.h>#include<stdio.h>BOOLConvertfiletimetolocaltime (ConstFILETIME *lpfiletime, SYSTEMTIME *lpsystemtime) {      if(!lpfiletime | |!lpsystemtime) {          return false;      } FILETIME ftlocal; FileTimeToLocalFileTime (Lpfiletime,&ftlocal); FileTimeToSystemTime (&ftlocal, Lpsystemtime); return true; }    BOOLConvertlocaltimetofiletime (ConstSYSTEMTIME *lpsystemtime, FILETIME *lpfiletime) {      if(!lpsystemtime | |!lpfiletime) {          return false;      } FILETIME ftlocal; SystemTimeToFileTime (Lpsystemtime,&ftlocal); LocalFileTimeToFileTime (&ftlocal, Lpfiletime); return true; }    intMain () {HANDLE hfile;      FILETIME ftcreate, ftaccess, Ftwrite;      SYSTEMTIME stcreate, staccess, stwrite; intYear , month, day; hfile= CreateFile (L"C:\\1.txt", Generic_read | Generic_write,0, NULL, open_existing, file_flag_backup_semantics, NULL); if(Invalid_handle_value = =hfile) {printf ("CreateFile Error:%d", GetLastError ()); ExitProcess (0); } getfiletime (hfile,&ftcreate, &ftaccess, &ftwrite); Convertfiletimetolocaltime (&ftcreate, &stcreate); Convertfiletimetolocaltime (&ftaccess, &staccess); Convertfiletimetolocaltime (&ftwrite, &stwrite); printf ("YYYY-MM-DD:"); scanf ("%d-%d-%d", &year, &month, &Day ); Staccess.wyear= Stwrite.wyear =Year ; Staccess.wmonth= Stwrite.wmonth =month; Staccess.wday= Stwrite.wday =Day ; Convertlocaltimetofiletime (&staccess, &ftaccess); Convertlocaltimetofiletime (&stwrite, &ftwrite); Setfiletime (hfile,&ftcreate, &ftaccess, &ftwrite);      CloseHandle (hfile); return 0; }
