modtime out of sync with network drive

modtime out of sync with network drive

[Dave]

Hello,

I am using emacs 22.2.1 on ubuntu 9.04. I have a network drive attached
(Buffalo linkstation pro duo - I think it's a samba share) and I have
the drive mounted automatically as a cifs filesystem. This works fine
for everything I do in ubuntu - permissions, running commands, copying etc.

The only problem I have is that when I'm editing a file on the drive in
emacs, everytime I save the file the buffer recorded modtime and file
attribute modtime get out of sync. This means the next mod I make to the
buffer I get the 'file has changed on disc etc' message. This is a real
hassle.

As an example, immediately after a recent save, the modtime as given by
visited-file-modtime was 9454, but by file-attribute was 9438. These are
both different to the value before the save which was 9407 for both.

Any help gratefully appreciated.

thanks
Dave

Use NTP to ensure that the clocks on your computer and server are in 
sync.

Thanks - I'd thought ntp was already on on my drive, but it wasn't. That
seems to have worked.
