Please add a comment about expected origin and resolution of modificationTime.
  e.g. 0 is Unix epoch, unit is msec.

I'm not an OWNER, so feel free to ignore this comment if you disagree, but I
think lastModified would be a better name here, because it maps to a concept in
the File API spec, which browser developers are likely to be familiar with.

I named it after FileMetadata's member.
https://code.google.com/p/chromium/codesearch#chromium/src/third_party/WebKit...

It looks the name is referring File System API's metadata name.
http://dev.w3.org/2009/dap/file-system/file-dir-sys.html#widl-Metadata-modifi...

So let me keep the name as it is.

Done.
