Anyway, your code is correct. Though it can be simplified to

Documented here:

The server behaves as if it is in UTC zone. If not, it's broken or misconfigured.

And I also do not understand the upload test. At 09:28:42, you upload a file modified at 22:39:28 file (both UTC).
The server does not seem to support changing a modification time:

> 2016-11-30 09:28:44.522 MDTM 20160929223928 paris_2016_c_155.jpg
< 2016-11-30 09:28:44.670 550 Could not get file modification time.

So the file should have modification time set to the upload time (09:28:42).

But after upload the time is 04:15. I do not, see where that time comes from. It cannot be explained by a -5 zone.

I've been testing the following code to generate proper values to TimeDifference raw settings and it seems to do the job.

Invoke with:

TimeSpan offset = new TimeSpan(1, 15, 0);

string TimeDifference = GetTimeDifference(offset);

I have uploaded (using winscp) a file named 00000 for /pub/incoming of the following public ftp server ftp.swfwmd.state.fl.us:21
After that I've executed my test app (using .net assembly) and issued a session.ListDirectory() and the log shows the following:
My local time was 2016-11-28, 11:16:00 and the server time was 2016-11-28, 06:16.

Please attach a complete log.

Good morning,

here is a complete log.

client time zone UTC
server time zone UTC-5

Execution steps:

1) Using winscp navigate to /pub/incoming
2) Using winscp upload a local file paris_2016_c_155.jpg into /pub/incoming
3) Using winscp to navigate to /pub/incoming and check that the time difference.
