just realized a strange behavior/bug in WinSCP 4.3.5 using FTP over SSL:
When I synchronize a directory more than once, differences show up which are not correct. For example a difference is shown on a file with local timestamp "27.12.2011 20:36:39" and remote timestamp "27.12.2011 20:36". (Note the missing part for seconds in the remote timestamp, maybe that's somehow related to the issue). File size is the same on both sides.
See also attached screenshot for details.
Closing and opening WinSCP solves the problem for the next run. After that run I have to close & reopen again to make sync work for the next time.
Thanks for help,
