Uploading Time Data in Negative Time Management ?

Dear All

We have a situation wherein we are going for negative time management but the Time Machine i.e., Swiping Machine is not directly connected to SAP R/3 server. We want to download the data from the Time Machine and upload the same into R/3 using a Batch session. Can some body tell me how this can be done. What are the inputs required for this file,the necessary data template(fields) and how the same is to be uploaded.

Thanks in advance,
