Wanted to set the time on a remote server my client computer is connecting to, and thought I would turn to a very useful utility originally created by "SysInternal" (now owned by Microsoft) called "PsExec".

Ran the following command:
C:\>psexec \\myGreatServer -u administrator -p mySecretPassword -S cmd.exe "/C TIME 11:52"
which output the following"
PsExec v1.98 - Execute processes remotely

Sysinternals - www.sysinternals.com

The system cannot accept the time entered.
Enter the new time:
The last two lines were obviously unexpected, and I had to hit the <Enter> key to get the command to complete its processing, at which point it spit out:
cmd.exe exited on myGreatServer with error code 0

I did think to try the /i option, but that just hung (apparently) the command when it ran.

Any thoughts on what is wrong?
The server is Windows 2008 Server and not a member of a domain. The client is running Windows 7 Pro and is part of our corproate's domain.
