If the cheaper unit is accurate enough, then it should work since they all output the standard NMEA CCGGA codes which contains the time-stamp. (I haven't looked at the source code to see if that's the message format the code uses.) If that's too much, you can get a Garmin 12 for around $180 (Cabela's Spring catalog) which has less 'features', but that's not important for doign time-clocks, unless you *need* an external antenna which the 12 doesn't support and the 12XL does. The antenna for the 12XL runs about $90 according to Cabelas, and the power supply is $19.. > 2) Poul is playing around with the Motorolla UT Oncore Evaluation Kit. > From what I gather, the "Evaluation Kit" is what you would actually end up > using.

The Garmin certainly doesn't require any device, just a funky cable to plug into the back of the unit that terminates in a standard db9 serial cable. Nate
