Perhaps a little format hacking is in order

In[1]:= Map[Flatten[{DateString[AbsoluteTime[First[#]]], ToExpression[Rest[#]]}] &, 
    StringSplit[Rest[StringSplit[StringReplace[Import["testdata.txt"], "," -> "."], "\n"]], "\t"]]

I'm not exactly certain how you want to apply the data, but perhaps with a little study you can see how to adapt this.

If that isn't enough then perhaps you can show one line of input and the needed output form of that.

Thats nice but please look to my attachment, I have to process such files. I use StringReplace[Import["testdata.txt"], "," -> "."] // Table
