[Bug 16969] New: utime/stat not accurate enough (truncation to integer occurring?)

http://bugs.winehq.org/show_bug.cgi?id=16969

Summary: utime/stat not accurate enough (truncation to integer
                    occurring?)
           Product: Wine
           Version: unspecified
          Platform: Other
        OS/Version: other
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

this is again from the python regression tests, test_os.py.
the result is that os.stat.st_mtime returns 1159195039.00

if get_file_system(test_support.TESTFN) == "NTFS":
            def test_1565150(self):
                t1 = 1159195039.25
                os.utime(self.fname, (t1, t1))
                self.assertEquals(os.stat(self.fname).st_mtime, t1)

That's a limitation of ext3.  ext4 will have microsecond timestamps.

The program

import os
t1 = 1159195039.25
os.utime("foo.dat", (t1, t1))
print os.stat("foo.dat").st_mtime
print t1

prints out two different values even in linux's python because of this.

sorry, i should have said: the test is only done when the
filesystem is detected as NTFS.

... you're lying about the filesystem type, therefore ... it fails!

True!  So, marking as WONTFIX rather than INVALID.

To work around this, run the test on an ext4 filesystem.
