Ive often had to write Arduino sketches and small PIC programs to read data from sensors for transmission to a PC over the serial link. This is mostly for testing and evaluating sensors in the lab � so I dont want to waste any more time than I have to writing software.  

A common requirement is to have each sensor record time tagged. However implementing a real time clock on a Arduino, PIC etc can be a lot of hassle. It makes more sense to tag the record on the PC as it comes in.

Here is a short bash shell script that runs on a Linux PC which reads data from an input stream (usually the serial port) line by line and prefixes each line with the unix epoch time (seconds since 1 Jan 1970):

#!/bin/bash

while read line ; do echo `date +%s` $line done 

So, for example, right now I have an Arduino sketch polling a SHT75 temperature humidity sensor. The Arduino is writing a record (about 1 every second) with the current temperature and humidity. The data looks like this:

19.70 49.22 19.70 49.38 19.68 49.38 19.66 49.22 

1323808719 19.70 49.22 1323808720 19.70 49.38 1323808721 19.68 49.38 1323808723 19.66 49.22 

The data can now be plotted with the insanely useful gnuplot utility like this:
