Max Integer Size for <FileTimeTolerance Seconds>

[Basil Rathbone]

Does <File Time Tolerance Seconds> have a maximum size?

i.e. Can I set <FileTimeTolerance Seconds="86400"/> for 24 hours?

This setting should probably be removed. There exists no file system to my knowledge that creates offsets larger than two seconds. In theory this setting could be useful if you never use FAT* and be set to 0.

Before FreeFileSync, I used rsync to backup my local external drive (Linux Mint 19.3/exFat) across an ethernet link to another exFat drive running under Raspbian Linux.

FreeFileSync insists on re-copying all that data for some reason (14TB at 100 Mbps)

It appears to be a timestamp issue and I just thought setting <FileTimeTolerance Seconds> to 24 hours might eliminate any timestamp issue(s)

That's what the "compare by file size" comparison variant is for.
