Bill, I did say _today’s_ RTP chips :)
Although as a Mac user with multiple types, many not Internet-connected, I’ve never seen any lose minutes per day. You might have a dead clock battery. -mel On May 2, 2019, at 7:57 AM, William Herrin <b...@herrin.us<mailto:b...@herrin.us>> wrote: On Wed, May 1, 2019 at 8:35 PM Mel Beckman <m...@beckman.org<mailto:m...@beckman.org>> wrote: I can tell you how the GPS server behaves when it loses it signal: it stops giving out verified time and lapses into Stratum-“goners” mode. But today’s RTP chips don’t start losing seconds-per-day when they are free running. Typically they might lose ten seconds per week on cheap systems. That’s of little concern if you have two GPS clocks. The macbook my employer issued gains about 20 minutes a day when not synced. Easier to not replace it because oh look, the drive is soldered to the motherboard. I've taken to calling it my crapbook. Really disappointed with the quality out of Apple lately. -Bill -- William Herrin ................ her...@dirtside.com<mailto:her...@dirtside.com> b...@herrin.us<mailto:b...@herrin.us> Dirtside Systems .........
