Server Filezilla 0.9.4.1 (win 7)
Server seems delivering file time as GMT absolute (can be seen using Filezilla Client)
while WINSCP get file time as GMT+ TZ ajusted. (can be seen in Dual pan display)
This forbid use of synchronize and keepupdated on filezilla (and probably other servers)
Rather a fundamental defect! (or lack of ease to find options to compensate, I didn't find any nor docs)
Proof:
If client workstation is set at UTC (GMT+0):
Then it work (do not transfert too many files)
very frustrating.
We will have to write our own FTP client rather than using WinSCP
