NTFS file time
Thu Mar 25 11:50:00 GMT 1999
I encountered a strange problem today while using "cp -pu" to backup
my local NTFS files to a remote samba drive. The cygnus tools (ls and
cp anyway) are not consistently reading and preserving the file's
modification time. In some cases there is a discrepancy of a two
seconds compared with what Win Explorer reports. This doesn't sound
like a big deal but it makes a difference when I only want to update
changed files and they are ALL apparently a second newer than their
backup copy, forcing all files to be re-copied.
If I copy the files using Win Explorer and then check properties, the
times are identical according to Explorer. The cygnus ls -l --full-time
command disagrees. Here's an example of what happens with cygnus
~ $ls -l --full-time a.ps
-rw-r--r-- 1 costerwi None 30613 Tue Mar 02 13:32:59 1999 a.ps
~ $cp -p a.ps //z
~ $ls -l --full-time //z/a.ps
-rw-r--r-- 1 costerwi None 30613 Tue Mar 02 13:32:58 1999 //z/a.ps
Notice the remote file is one second older than it's original, forcing a
future "cp -pu" to copy the file again (and again miss the time)!
Is there any way I can resolve these differences? Any help would be
