I have a simple script for uploading files to our linux server. When I use the script to transfer a file, I often (not always) get the following error: "Copying files to remote side failed. Invalid argument to time encode." Sometimes, the transfer will be successful. It seems more likely to fail with larger files, although I haven't been transfering extremely large files - these are on the order of 50MB. If I attempt to transfer the same file 10 times in a row, it might be successful 2 or 3 times out of 10.

One more thing. If I open the WinSCP GUI (commander mode) and transfer the file, it works every time without fail, even for very large files.

On the local side, I'm running the script via a dos batch file under windows XP X64 SP2. I have WinSCP 4.2.7 (Build 758) installed. The remote system is a 64bit Linux server.

Here is the dos script:

@echo on
@echo off
rem
rem set server user name and password
rem
set USER=username
set PASS=passwd
rem
rem ***************************************************************
rem BEGIN: Generate temporary winscp script to upload and run files
rem ***************************************************************
rem
echo option batch on > runscript.tmp
echo option confirm off >> runscript.tmp
echo option reconnecttime 1000 >> runscript.tmp
echo option transfer automatic >> runscript.tmp
echo open %USER%:%PASS%@atc-pbs00 -timeout=100000 >> runscript.tmp
echo cd /stage/jobs/rmorris/QTEST >> runscript.tmp
echo put -resume -nopreservetime -nopermissions upload.zip >> runscript.tmp
rem echo close >> runscript.tmp
rem echo exit >> runscript.tmp
rem
rem ********************************************************
rem END: Generate temporary script to upload and run files
rem ********************************************************
rem
winscp.exe /console /log=winscplog.txt /script=runscript.tmp
rem
@echo off

Next is the winscp script used to pass the file:
option batch on
option confirm off
option reconnecttime 1000
option transfer automatic
open rmorris:Jason1@atc-pbs00 -timeout=100000
cd /stage/jobs/rmorris/QTEST
put -resume -nopreservetime -nopermissions upload.zip

I have tried it with and without the -nopreservetime/-preservetime and -nopermissions switches.

Finally, below is the log file contents:

Your timeout of value of 100000 seconds is too great. WinSCP cannot convert this into a time value. Use something below 86400 (24 hours).

Thanks Mikk! I made the change and have run the script several times without any failures. It seems to have done the trick!

I'm having the exact same problem, but my timeout is already low, like 30-60 seconds. Any other ideas?
