There's a software tool called Kalibrate for use with the GNU Radio software and USRP radio hardware, which uses GSM base station signals as a standard to measure the frequency offset of the USRP's oscillator. It's not really a time-nutty application, but it serves as an example of using cellular base stations as a frequency reference. http://thre.at/kalibrate/ GNU Radio is a free open-source development environment for implementing software-defined radios. The USRP is one of the more popular RF hardware options for use with GNU Radio. http://gnuradio.org/redmine/wiki/gnuradio -- Mark J.
