as noted in Bug 52, synchronization PC/UNIX does not work because of difference in file sizes and daylight issues. I would like to suggest a quick fix: Could we have an option to consider the time equal if the difference is less than x seconds?
This should be quick and would solve my problems. I am currently using the (non-free) InstantSync software that has precisely such an option, and I set the time difference to a tiny bit more than one hour. (Suggestions of other free software that allows for that would be appreciated too!)
