Thanks a lot .. we will update to 5.9.1 and as first step : synchronize timestamps
Regards
Juergen

Thanks.

It's most probably due to this change:
https://winscp.net/tracker/1060

If you want adjust the timestamps of local files to avoid to re-download them all, run one-time timestamp synchronization.
See the Synchronize timestamps mode:
https://winscp.net/eng/docs/ui_synchronize

Actually I couldnt do the synchronize .. but in the /log you see the result of the dir command ... that should be the basis for the synch ... isnt it ?
Hope its enough information for you.

synchronize local -delete -mirror %TARGET_DIR% %SOURCE_DIR%

So please attach a session log file for that (from both versions).
Use the /log=... command-line switch.

Thanks for the logs. Though I do not see any difference. Can you name one specific file that you have the problem with?
How exactly do you check for the difference? Maybe some screenshot may help explaining the problem.

lcd %TARGET_DIR%

option confirm off
synchronize local -delete -mirror %TARGET_DIR% %SOURCE_DIR%
dir

Screenshots added ...
You see 1 hour difference ...
If I start synchronize now, my job would detect every file as "new" and synchronize everything -
In my case, that would be some 60 GB of data and ... I have problems with post processing, because these data have already been processed.

Hi Martin ... I uploaded the logs for both versions.
Thanks in advance ...

Please post a full session log file from both versions.

Hi ..
while testing migration from 5.1.0 to 5.9.1 we experienced a timestamp problem.
5.9.1 file/dir listing of change date shows 1 hour less than 5.1.0 version.

If we would move to new version, our synchronize would recognize all files as changed ... not good

- we use SFTP and synchronize function.
- Environment config for both installations:
- Daylight saving time : Adjust remote timestamp to local conventions
- tests from same client to same server with same user.

Any ideas what could be the problem ?
