Re: [time-nuts] x86 CPU Timekeeping and clock generation

Wow! Thank you for all the answers! I'm really happy... D. Rasor, Thank you for the file, i will take a look closer on it. Hal Murray, I have the same thought of you, but when I tried in an ARM Single Board Computer (Asus Tinkerboard) with the same scenario (external clock and no syncing in NTP)

[time-nuts] x86 CPU Timekeeping and clock generation

Hi all, I'm studying computer's timekeeping and i'm on level of remove the base crystal that feeds the entire PLL logic of the motherboard (24 MHz on motherboard that i'm using) and compare system's time with an NTP server. The 24 MHz comes from an synthesizer that is locked to an atomic clock, t

Re: [time-nuts] chrony vs other NTP

I think chrony is better suitable to who wants more customization options, such as faster pooling times, better delay calibrations and advanced filtering settings (i dont know all on Openntpd nor chrony) but with my experience with chrony i can say that chrony is good for my usages. Em qui, 26 de

Re: [time-nuts] Noob question, NTP stratum 1.

Dear colleagues, i've made some tests and wrote an article about Raspberry Pi as a timeserver. I think we can trust on it and this board can keep a good time from GNSS PPS. I'm open to suggestions. I hope this can help in the decision making process. The link: rpi_article

Re: [time-nuts] Advantages of GNSS ???

Hey Graham, I'm gonna start a project soon to evaluate a F9P as a Time Transfer GNSS receiver. For now i haven't too much answers for you but only i know is: the BIPM uses all labs that participate from UTC to make corrections of GNSS satellites frequency, also for the TAI use. I think GNNS T&F is

Hi friends, We have a hydrogen maser here at the university that i work. It seems the hydrogen is over. This is possible? If yes, It is possible to recharge It? Best regards, Luiz. ___ time-nuts mailing list -- time-nuts@lists.febo.com To unsubscribe,
