java - How to set last modified date using TrueVFS -

How do I set the last modified date of a file using TrueVFS? Because accordingly () it should be as simple as

  file entry = new TFile ("archive.zip/dir/HälloWörld.txt"); Entry.setLastModified (System.currentTimeMillis ());  

but it does not work for files , but if I do the same for folders then it works .

This is what I am using

  string NUMBER_FILE = "C: /333/ServerEAR.ear/1.txt"; String newLastModified = "11/12/1999 14:15:16"; SimpleDataformat SDF = New SimpleDateform ("DD / MM / YY HH: mm: SS"); Long new data = sdf.parse (newLastModified) .gettime (); File entry = new TFile (NUMBER_FILE); Boolean Result = Entry .customly modified (newadet);  

Although the result is correct, the date I want is not modified
