I was pleasantly surprised today firing up my old KIWI time stamper
after a year in hibernation.  The stamper uses a Garmin 18LVC for
precision time stamping designed for astronomical occultation timings.
Showed the correct date and made it to GPS week 2048.

GPS 18LVC board ver. 8 - software ver. 2.60
ROM checksum test (P=pass, F=fail) = P
Receiver failure? (P=pass, F=fail) = P
Stored Data (L=lost, R=retained) = R
Real time clock (L=lost, R=retained) = R
Oscillator drift (P=pass, F=fail) = P
Data collection (C = collecting) =
Board temperature (degrees C) = 22

Cheers,
Gary
