I am trying to use rsync to synchronize files to a Windows computer over Samba but the recent daylight savings time change has changed the files on one of the computers. So rsync -run threatens to update _all_ files instead of just the few recently changed ones because they are different by 1 hour. I made an alias to include "--modify-window=3666" but it doesn't seem to be working because it still wants to update all the files. The alias is: rsync.hour='rsync -vpogt1D --modify-window=3666' What's the maximum value of --modify-window? Can it be changed? Larry Alkoff Larry Alkoff N2LA - Austin TX
