Using rsync to synchronize timestamps between -besides the timestamp- equal files.
(command line: rsync -vtpr [source] [destination])
source drive is a NTFS network drive, mounted with Samba
destination drive is a mounted build-in NTFS drive

The rsync runs without error. When monitoring the changes through Thunar, at first, Thunar doesn't show the modified timestamps. Even reloading (button on the toolbar) doesn't change the display. Only when closing Thunar and relaunching it, the modified timestamps are shown correctly.

On my machine, the bug is reproducable. It took me some time before I realised the bug was in Thunar. As I am not so familiar with rsync, I thought I was giving it wrong parameters on the command line. And at some point only a directory showed a modified timestamp ...

Might have to do something with next message ?

Am I right that rsync first creates a dot-file to apply changes ?  Maybe some cache doesn't get refreshed when only the timestamp is changed ?
