10MHz output will be reference for a couple frequency counters and an osc in the workshop. port2 time-of-day will feed an embedded Linux solution for doing SNTP/NTP and PTP grandmaster servers to share on the LAN. PTP grandmaster will be the main clock for a 12 channel AVB (audio video bridging 802.1av) audio setup in my home theater as well as other AVB experiments in the workshop. In a sense, it doesn't really matter about precision clock as my NetGear GS724T managed switch already has has a fallback grandmaster. As time is relative, the once-per-minute jumps due to SNTP requests from the switch effect everyone equally at the same moment. If I was using PTP for frequency generation, which I just might intend to do in the future, it should matter. I hear ya. I'm just a hobbyist. OMNICRON is for the business solution searchers https://www.omicron-lab.com/shop/PTP-Grandmaster-Clocks.html Thanks for the battery clue, I'll have a look. -- [email protected]:~$ make war make: *** No rule to make target `war'.
