>Dear Tim, Martin,
Thanks for helping with this. I tried setting TZ=UTC at both ends, and discovered that for some reason the files had a 1-hour timestamp difference. Not sure how that happened, but clearly not an rsync problem. I have added a note on this to my web page for PC users (http://optics.ph.unimelb.edu.au/help/rsync/rsync_pc1.html): rsync tries to convert all file timestamps into UTC at both ends. If seemingly identical files with the same timestamp seem to be transferring, try this at both ends: export TZ=UTC ls -l --full-time file_in_question If the remote and local files have the same timestamp, and they're still transferring, then you have a different problem. BTW, I have recently found another problem with using rsync on Windows/cygwin platforms. I had an exclude/include file list in dos format (cr/lf pairs instead of newlines). Oh boy did that create some fun. include/exclude rules are funny enough without the weird behaviour of matching added CR's. In my rsync scripts I now run dos2ux on these lists before executing rsync. Thanks again for your help. I live and breathe by rsync now that I'm 20,000km from hom.
