| | Local file system is FAT | File timestamp is always rounded to the next even second. This is a limitation of the legacy FAT filesystem. For this reason WinSCP ignores less than 2-seconds time difference with all its [[task_synchronize|synchronization]] features. Although FAT is an old filesystem, it remains in common use today on flash based storage media and devices (such as USB flash drives, camera cards, phone internal storage, portable audio players etc). Standard ZIP archive files also use a similar timestamp system internally, so unzipped files will behave as if they have been copied from a FAT filesystem. | | | Local file system is FAT | File timestamp is always rounded to the next even second.

| | Timestamp precision | Files changed again shortly after a previous change are not synchronized if the server does not provide timestamps with sufficient precision in a directory listing.((You can see in the remote [[ui_file_panel|file panel]], with what precision does WinSCP know the remote file timestamp. So if panel shows e.g. ''dd/mm/yyyy hh:mm'' (minute precision), then if you change already synchronized local file within the same minute, WinSCP cannot recognize the change and won't synchronize the file.)) [[SCP]] and [[FTP]] protocols are affected. \\ WinSCP remembers timestamps of files uploaded in the session. When synchronizing the previously uploaded files, WinSCP will use the remembered timestamp instead of imprecise timestamp provided by the server. &beta_feature | | | Timestamp precision | Files changed again shortly after a previous change are not synchronized if the server does not provide timestamps with sufficient precision in a directory listing.((You can see in the remote [[ui_file_panel|file panel]], with what precision does WinSCP know the remote file timestamp.
