+**Issue:**
+
+Synced folders appear with wrong timestamp.
+
+**Resolution:**
+
+On POSIX systems the semantics of timestamps is special. The timestamp is updated, whenever a file is created or removed,
+but it is not updated, when file contents or contents of subfolders changes.
+
+We do not sync the timestamps of folders for this reason.
+Users are advised to not rely on timestamps of folders.
