Enabling DST (the summertime and wintertime schedules across the globe) within your time zone might cause an unexpected shift in datetimes by 1 hour when you're trying to set filetimes with FileSetTime or read them with FileGetTime. This behaviour frequently causes bugreports like #3139 at https://www.autoitscript.com/trac/autoit/ticket/3139 'FileGetTime out by exactly one hour.', where it was classified as 'No bug'. Now this isn't considered a bug when you're referring to the datetime as shown by the command prompt (DOS prompt, even in Windows 7+) or Windows Explorer XP, as these programs use 'old style' DST behaviour. But it definitely can be considered a bug when you're using Windows Explorer 7+, which adopts the 'new style' behaviour. 'Old style' (currently implemented, v3.3.14.2 and previous) calculates datetimes as follows: FileSetTime = local time - time zone - DST currently in effect FileGetTime = file datetime + time zone + DST currently in effect whereas 'new style' calculation of datetimes would require: FileSetTime = local time - time zone - DST in effect at the time of the file's datetime (Dynamic Time Zones) FileGetTime = file datetime + time zone + DST in effect at the time of the file's datetime (Dynamic Time Zones) This 'new style' behaviour will leave your timestamps unaltered in Windows Explorer 7+ whenever a transition to summertime or wintertime occurs, but requires detailed records of all DST schedules worldwide. Fortunately all these records are readily available in Windows 7+! You can read more about this in Raymond Chen insider blogs at https://blogs.msdn.microsoft.com/oldnewthing/20130308-00/?p=5023 and https://technet.microsoft.com/en-us/magazine/ff394358.aspx To have FileSetFile and FileGetFile adopt the 'new style' DST behaviour, I've written FileSetFileExt and FileGetFileExt. As part of FileSetFileExt, which has an option to recurse into the given path, the function FindFiles was created. It's included separately and you can easily apply it as a stand-alone function to recurse a given path and process all files that match a specified pattern. I think it's a useful function that AutoIt unfortunately still lacks.

no web server atm. so the win7 file properties images I can't show you but they are totally different from the variables I am getting..But then I am just guesstamating the code needed from any and all sources i can find to just get the Minutes difference between 2 files. I can touch the files to change anything, but can't get the value to use it and using FilesetTime/ only works with the Help code. and it is way over my head. I have searched the web looking for a step by step but it's all in arrays that array me. The FileSetTime ;Modified help file #include <FileConstants.au3> #include <MsgBoxConstants.au3> $sFilePath=("C:\file1.txt") Local $iFileSetTime = FileSetTime($sFilePath, "20031101121101" ) ; Display the modified timestamp of the file and return as a string in the format YYYYMMDDHHMMSS. If $iFileSetTime Then ; MsgBox($MB_SYSTEMMODAL, "", "Timestamp:" & @CRLF & FileGetTime($sFilePath, $FT_ACCESSED, 2 )) RETURNS Timestamp: ; MsgBox($MB_SYSTEMMODAL, "", "Timestamp:" & @CRLF & FileGetTime($sFilePath, 2 )) RETURNS Timestamp: ; MsgBox($MB_SYSTEMMODAL, "", "Timestamp:" & @CRLF & FileGetTime($sFilePath, "YYYYMMDDHHMMSS" )) RETURNS Timestamp: ; MsgBox($MB_SYSTEMMODAL, "", "Timestamp:" & @CRLF & FileGetTime($sFilePath, $FT_MODIFIED, 1)) RETURNS Timestamp: The only one that returns Anything is the last one and it returns the whole string..Timestamp:20031101121101 ; RETURNS Timestamp:20031101121101 File Properties accessed time and date ?Saturday, ?November ?01, ?2003, ??1:01:00 AM File EndIf changed created date but displays YYYYMMDDHHMMSS" So I got creative and after /////..... and more of that got this to work..

Using FIleSetTime() to update the Date Modified tag on a copied file.

Tested my above code and it seems to work fine, so I suppose the NAS is the problem.
