Description:

Using curl I can apply an mtime to a MFS file with /api/v0/files/touch but not with /api/v0/files/write.

Steps to reproduce the error:

% curl -X POST "http://172.30.16.17:5002/api/v0/files/touch?arg=/users/mrh-i/t.txt&mtime=1697263111"

% curl -X POST -F [email protected] "http://172.30.16.17:5002/api/v0/files/write?arg=/users/mrh-i/x.txt&mtime=1697263111&create=true"

% jsipfs files ls -l /users/mrh-i/

ipfs.files.write takes args as a multipart request, including specifying the mtime as a header in the multipart part.

See how the http client does it for an example: https://github.com./ipfs/js-ipfs/blob/master/packages/ipfs-http-client/src/files/write.js
