Cant get "file modified" date column to work

[GoogleCodeExporter]

What steps will reproduce the problem?
1. add to index.html:
"list-view-columns": {
                        "name": {title:"fileListColumnTitleType"},
            "file-modified": {},
                        "type": {title:"fileListColumnTitleType"},
                        "size": {title:"fileListColumnTitleSize"}
                }

What is the expected output? What do you see instead?

I should get a new column with the date of the file, and get this error instead

Protocol error

Got malformed JSON response: 
Fatal error: Call to undefined method 
ServiceEnvironment::formatTimestampInternal() in 
D:\(...)\backend\include\filesystem\CoreFileDataProvider.class.php on line 28

What version of the product are you using? On what operating system?
1.8.7.1

Please provide any additional information below.

If I take ""file-modified": {}," all works fine, but no date...
the file date works on the details
