Hi, I have seen you are using Lassen SQ GPS. I am using it to put in hour a seismograph net. The timing system is formed by a Lassen SQ GPS, RTC from PHILLIPS and a LCD (and a microcontroller). When the GPS system have UTC time in the lcd appears two asterisc indicating that i have UTC time, then UTC time pass to the RTC and i can to put in hour the seismograph through I2C. After 3 month i have seen that time stored in the seismograph is in GPS time not in UTC time, but specifications of GPS says it only sends UTC time, it is correct??.
thank you, sorry for my english.
