[teqc] helpful tip of week 2027

Dear teqc experts,

We have some NETRS data and converted it from *.T00 to *data format using runpkr00.
Now we want to make RINEX files.  These data files were created on Julian day 313 when we tested the receivers and we did our real data collection on day 316.
When we run teqc it extracts up until the week boundary so we do not get the data from day 316.

Is there a command line flag to ask for a particular day?

Thanks,

David and Hugh
