Will this work for you?

$ git show -s --pretty='%cd | %an' --date=format:%FT%R:%S 2017-02-02T10:01:36 | G. Sylvie Davies

I have no idea how portable this might be.  As "git help log" says:

         --date=format:...  feeds the format ...  to your system
strftime. Use --date=format:%c to show the date in your system
locale’s preferred format. See the strftime manual for a complete list
of format placeholders.
