Interesting. Does it work without the ".318491822" but keep the "Z"?

How about if you replace ".31849182" with ".000000000" while keeping the 
"Z"?

Can you strace the 'touch' and see what system calls are failing and 
what their arguments are? On my platform, if the file /tmp/foo already 
exists and is writeable, then the command:

strace touch -d 2019-02-14T18:23:17.318491822Z /tmp/foo

outputs:

...

dup2(3, 0)                              = 0
