Trying to change time only; no success

[JayEmBee]

Greetings forum moderators,

I am trying to change the time only with the following command:
exiftool "-CreateDate<${CreateDate;s/ .*/ 00:00:00/g}" temp

I would like to remove all references to time in the file.
I get Warning: No writable tags set from temp error

exiftool -a -G1 -s temp results in:

[ExifIFD]      CreateDate                      : 2016:09:18 21:45:15
I would like it to read:

Thank you advance

Your command should work for CreateDate if you are in a Windows cmd shell.  For other shells you need to use single quotes.
