SSV (Set System Value)command will change the system time in the CPU.
You'll have to make sure the value you dump in there is the correct format, I use Rockwells TimeSynch tool to do all mine as its alot easier than fooling around with SSV's and datetime formats.

are you just trying to MANUALLY change it? ... if so, try this ...
If you utilize the EWEB module, it can retrieve the time from a time server and set the controller. Pretty neat feature.
Another way would be to set it manually.
Our system uses a time sync pulse from a central controller and sets the time accordingly. You have to use the SSV instruction to set the wallclock time. Be aware, firmware version 16 and above has a different wallclock as version 15 and below.

Instead of using GSV, use SSV (SET system value) this will set the CPU clock to whatever value you move in there. If you just want it to synch to a PC clock then use the Rockwell TimeSynch tool - much much easier.

If you wanted time to be dead nuts on you could put in one of these: http://www.hiprom.com/Products/1756hpGPS/1756hpGPS.htm

Are you talking about the Logix5000 Clock Update Tool?
Is it possible to use an NTP or SNTP server instead?
