I'm not talking about missing an update. Quite the contrary. I'm talking
about duplicity wanting to back up all my files during an incremental
run due to e.g. 1189972184.36 != 1189972184.00 ?
Or are you perhaps discussing the correctness of doing subsecond
timestamp granularity in the backup volumes?
