Neither of the solutions I posted earlier in this thread are dependent on timestamps.
iirc: Especially for online backups rdiff-backup mentioned before ignores timestamps altogether. It calculates the MD5 for every file to see if any changes have been introduced. If they have it segments the file and drills down to find the smallest unit of change and only sends that data across the LAN/WAN.

Thanks. I have taken a look at your suggestions and that of Joachim, I am impressed with the description of both. XFS is not an option as it looks like I would have to do a lot of partition juggling to make a move.
Unfortunately, as there are problems with my tape unit I am for the moment constrained by the need to backup to DVD/CD, and it is not immediately clear to me how either dirvish or rdiff-backup would effectively work in this situation, but I will be looking into this further. (Actually, the more I have explored the DVD/CD element of the problem, more I understand why no-one has produced a usable DVD/CD backup solution). I have already decided that for the code I am working on I will be using subversions backup procedures to dump the repositries, and I will be dumping MySQL databases as well (probably will eventually run queries that only dump new records or modified records), which largely leaves the backup of Documents, Spreadsheets, etc etc to something else (rdiff-backup seems to be the front runner here).. e-Mail structures are going to be a particular headache.
If you need to back up to DVD/CD what about Mondo/Mindi I used to use it exclusively for several years a while ago. Now I use Kdar but I back up to a spare hard drive. Just a thought.
