I have configured a one way sync from Host A (v0.14.39, Windows (64 bit)) to Client B (v0.14.39, Linux (64 bit)) and Client C (v0.14.39, Mac OS X (64 bit))
I recognized, a constant out of sync on some files with filedate 01.01.01. 01:00:00
After pressing the “Overwrite Changes” Button, syncing is done and after some time, “out of sync” appears again.
Those files are correctly synced from the Host A to the Clients B+C, but the filedate seems to have not preserved.

I’m not sure I’m 100% following but I interpret it that you are trying to sync files with the modification time 0001-01-01 01:01:00 (i.e. some time in year one) and this doesn’t work. If so, I think this is expected. Mac HFS+ can’t represent times before 1904, and ext2 (and presumably later variants) begin at 1901. We have some special handling of setting mtimes as that often breaks, so I think we should not become out of sync, really, but …
Workaround: Use a date within the last century or so…
