Sending timestamped values

The data that we sent so far was considered to be received at that exact moment—the values had the timestamp assigned by the server when it got them.

For a quick test, we could generate timestamps one, two, and three days ago:

$ for i in 1 2 3; do date -d "-$i day" "+%s"; done  

Take the resulting timestamps and use them in a new input file:
