Update vclient.c

small fix to allow the output of system time in a csv file.

I think it's not good to have getSystemTime hard coded in vclient.c. It's just a tag in vito.xml, e.g.:

    <command name="getSystemTime" protocmd="getaddr">
      <addr>088E</addr>
      <len>8</len>
      <unit>TI</unit>
      <description>Ermittle Systemzeit</description>
      <device ID="2053"/>
    </command>

But I don't have a better idea right now ...

You are right, it's hard coded. But it helps people to simply output the system date... From what I saw on the web, I was not the only one with this problem.
