Например из даты создания файла реестра...Но тут непонятно, а будет ли работать это на разных операционках, как реализовать?

The GetFileTime function retrieves the date and time that a file was created, last accessed, and last modified.

BOOL GetFileTime(

HANDLE hFile, // identifies the file
LPFILETIME lpCreationTime, // address of creation time
LPFILETIME lpLastAccessTime, // address of last access time
LPFILETIME lpLastWriteTime // address of last write time
);
Parameters

hFile

Identifies the files for which to get dates and times. The file handle must have been created with GENERIC_READ access to the file.

lpCreationTime

Points to a FILETIME structure to receive the date and time the file was created. This parameter can be NULL if the application does not require this information.


lpLastAccessTime

Points to a FILETIME structure to receive the date and time the file was last accessed. The last access time includes the last time the file was written to, read from, or, in the case of executable files, run. This parameter can be NULL if the application does not require this information.

lpLastWriteTime

Points to a FILETIME structure to receive the date and time the file was last written to. This parameter can be NULL if the application does not require this information.

Return Value

If the function succeeds, the return value is TRUE.
If the function fails, the return value is FALSE. To get extended error information, call GetLastError.

Remarks

The FAT, NTFS, and HPFS file systems all support the file creation, last access, and last write time values.
Windows 95: The precision of the time for a file in a FAT file system is 2 seconds. The time precision for files in other file systems, such as those connected through a network depends on the file system but may also be limited by the remote device.

The GetSystemTimeAsFileTime function obtains the current system date and time. The information is in Coordinated Universal Time (UTC) format.

VOID GetSystemTimeAsFileTime(

LPFILETIME lpSystemTimeAsFileTime // pointer to a file time structure
);
Parameters

lpSystemTimeAsFileTime

Pointer to a FILETIME structure to receive the current system date and time in UTC format.

Return Value

This function does not return a value.

Remarks

The GetSystemTimeAsFileTime function is equivalent to the following code sequence:

FILETIME ft;
SYSTEMTIME st;

GetSystemTime(&st);
SystemTimeToFileTime(&st,&ft);


Windows 95: The GetSystemTimeAsFileTime function is not available on the Windows 95 platform. If you need its functionality, use the preceding code sequence.

VOID GetSystemTime(

LPSYSTEMTIME lpSystemTime // address of system time structure
);
Parameters

lpSystemTime

Points to a SYSTEMTIME structure to receive the current system date and time.

Return Value

This function does not return a value.

Remarks

Windows 95: Early beta implementations of this function return local time rather than UTC.
