solved: FileGetTime() getting ms information as well

[rudi]

Hello,

Propably not an absolute clean approach, (not checking/caring about little / big endian), but it's doing, what I need: Return the last modified time stamp including the milliseconds:

 

#include <Date.au3>


$file = "c:\temp\test.txt" ; file must already exist

$TSLastModMs = GetFileLastModWithMs($file)
ConsoleWrite('@@ Debug(' & @ScriptLineNumber & ') : $TSLastModMs = ' & $TSLastModMs & @CRLF & '>Error code: ' & @error & @CRLF) ;### Debug Console



Func GetFileLastModWithMs($_FullFilePathName)
    local $h = _WinAPI_CreateFile($_FullFilePathName, 2, 2)
    local $aTS = _Date_Time_GetFileTime($h)
    _WinAPI_CloseHandle($h)
    local $aDate = _Date_Time_FileTimeToArray($aTS[2]) ; [2] = LastModified
    Return StringFormat("%04d-%02d-%02d %02d:%02d:%02d.%03d", $aDate[2], $aDate[0], $aDate[1], $aDate[3], $aDate[4], $aDate[5], $aDate[6])
EndFunc   ;==>GetFileLastModWithMs

--- original posting - what was my problem, below ---

 

doing some search I found postings, stating that 2s will be the smallest time resolution for filegettime(). 2s seem to be fact for FAT as FS, NTFS has a much finer granularity.

 

This posting states, that NTFS has a granularity of 100ns:

https://superuser.com/questions/937380/get-creation-time-of-file-in-milliseconds

is it possible to get more than just the "second" information? The reason, why I need this is, that I need to sort files by their creation sequence, and it can happen, that two files are created within the same second, so I cannot resolve their creation order without "millsecond info".

 

Regards, Rudi.

 

edit: I just tried PowerShell, there it's possible to retrieve even more than millisecond information:

 

Millisecond : 336
Ticks       : 636719150403363219
TimeOfDay   : 11:04:00.3363219

 

PS C:\Users\Rudi> echo test > test.txt
PS C:\Users\Rudi> $(Get-ChildItem .\test.txt).creationtime | format-list

I just noticed, that there is a Function called Date_Time_GetFileTime(), that is returning a 3 elements array of $tagFILETIME, the function _Date_Time_FileTimeToStr() converts this to a human readable time stap, but also with just a granularity of seconds.

 

$tagFILENAME is something non printable. The help file is  telling something about parameters "hi" and "lo", no clue, how to use parameters with a $Variable? 

"struct; dword Lo;dword Hi; endstruct"

 

$tagFILETIME

Contains the number of 100-nanosecond intervals since January 1, 1601

Global Const $tagFILETIME = "struct; dword Lo;dword Hi; endstruct"

Parameters

Lo The low order part of the file time 
Hi The high order part of the file time

 

 

#include <Date.au3>

$file="c:\temp\test.txt"
$h=_WinAPI_CreateFile ( $file, 2 ,2) ; open existing file for reading
$aTS=_Date_Time_GetFileTime($h)
_WinAPI_CloseHandle($h)

for $a = 0 to 2
    ConsoleWrite("""" & $aTS[$a] & """" & @CRLF)
    ConsoleWrite(_Date_Time_FileTimeToStr($aTS[$a] )& @CRLF)
Next

Did you try with DllStructGetData() ?

@FrancescoDiMuro

 

...try ... DllStructGetData() ?

 

No. Maybe I should take a look at it. Anyway, as the updated, upper part of my OP is reflecting already, I've modified some code taken from Date.au3
