Can GNU tar incremental backup use checksums?

According to GNU tar manual: > Incremental dumps depend crucially on time stamps, so the results are unreliable if you modify a file's time stamps during dumping (e.g., with the `--atime-preserve=replace' option), or if you set the clock backwards. The timestamps on my file is one hour off, due to daylight savings time on the portable device. Is it possible to force tar to use checksums? (I'm thinking about using just about anything else because managing snapshot files seems very annoying and error-prone)
