Robocopy /DST switch doesn't seem to work

Question

I am trying to copy data between 2 GFS shares using a Windows server 2012 box as a pass through. Since Daylight Saving Time change. i noticed the files had a time difference of 1 hour on the source and destination. When i try to use the /DST switch i get a return that says invalid parameter. Any ideas on how to resolve?

Robocopy command:

robocopy Source Destination /E /ZB /FFT /DST /COPY:DAT /TEE /R:0 /W:0 /LOG:c:\Install\Batch\Logs\Data1.txt

output:

Started : Thu Nov 05 19:41:25 2020

Source - Source
Dest - Destination

Files :
Options : /FFT /S /E /COPY:DAT /ZB /R:1000000 /W:30

---

ERROR : Invalid Parameter #6 : "/DST"

  Simple Usage :: ROBOCOPY source destination /MIR

        source :: Source Directory (drive:\path or \\server\share\path).
   destination :: Destination Dir  (drive:\path or \\server\share\path).
          /MIR :: Mirror a complete directory tree.

For more usage information run ROBOCOPY /? or read Robocopy.Doc.

NOTE: Read "True Replication" in Robocopy.Doc prior to first use of /MIR !
*** /MIR can DELETE files as well as copy them !

Thank you,

Hi,
1.What if you remove /DST from your command, will other error message appear?

2.Kindly check the robocopy version and path via below command and verify if any old version existed.
gcm robocopy | fl *

Looking forward to your update.

Best Regards,

HI,

If i remove /DST, the copy runs. However it copies every file that is present in the source and destination as "Newer". I am trying to complete a delta sync to capture new and changed files.

Robocopy version:
PS C:\Users\cap_win03> gcm robocopy | fl *
