NEWS:

Version 0.14.0 - 1998-01-28
* reverse mirror (--reverse) (limited - no symlinks, no timestamps)

That's old, but has it been fixed??
That's precisely my problem.

ftp:timezone (string)
Assume this timezone for time in listings returned by LIST command. This setting can be GMT offset [+|-]HH[:MM[:SS]] or any valid TZ value (e.g. Europe/Moscow or
MSK-3MSD,M3.5.0,M10.5.0/3). The default is GMT. Set it to an empty value to assume local timezone specified by environment variable TZ.

"The option is not available with SFTP protocol, as with it, the server must report all timestamps in UTC."

Here is what I did at 17:18 GMT+8, i.e. 09:18GMT:

$ date '+%s' && touch apple

Using
set ftp:timezone +1
does not help.
I observe the same behavior and the same timestamps.

I used it in .lftprc
and I also tried live:

:/test> ll
drwxr-xr-x    2 1030     clients       512 Nov 25 10:37 .
drwx---r-x    6 1030     clients       512 Nov 25 03:41 ..
-rw-r--r--    1 1030     clients         0 Nov 25 09:18 apple
:/test> set ftp:timezone +2
:/test> ll
drwxr-xr-x    2 1030     clients       512 Nov 25 10:37 .
drwx---r-x    6 1030     clients       512 Nov 25 03:41 ..
