Modified date copy/paste weird bug?

I dont know if this is just my PC but if you have files with 20191230 09,46,45 date
OR if you apply 20191230 09,46,45 to some files via SetAttr MODIFIED="{clip}" CREATED="{clip}" and then copy (see below) this date, then this date will be changed to 20201230 09,46,45

I suddenly found it by copy/pasting modified date from 20191230 09,46,45 file...

Script that i used to copy dates, it never failed me until now, hehe.

@confirm Copy Timestamps?
Rename FILEINFO TO "{modifieddate|D#YYYYMMdd} {modifiedtime|T#HH,mm,ss}"

@script vbscript
Option Explicit
Dim strOpusHomePath
strOpusHomePath = "C:\Program Files\GPSoftware\Directory Opus\dopusrt.exe"
Dim Shell
Dim Clip
Set Shell = CreateObject("WScript.Shell")
Function Rename_GetNewName(strFileName, strFilePath, fIsFolder, strOldName, ByRef strNewName)
Clip = strNewName
strNewName = ""
Clip = Replace(Clip,"-",":") ' Set the clipboard via Opus.
Shell.Run """" & strOpusHomePath & """ /CMD Clipboard Set " & Clip,0,True
End Function

Again, im not sure that this is just my PC, because I have never seen this "bug" before.

SetAttr META "lastmodifieddate:20191230 09:46:45" (note the : instead of , in the time part) worked fine on a file here.

YYYY is the date code for the ISO year. Use yyyy for the calendar year.

P.S.: Full points for script creativity :wink:
