Picking up on an event about eztime

[ropg]

I guess you could turn off NTP updates with setInterval(0) and then from your own event call queryNTP (which doesn't actually set the time) and then setTime and whatever else you want to do. How about something like this. (Untested...)

[...]

void setup() {
    [...]
    setInterval(0);
    timeSyncEvent();
}

void timeSyncEvent() {
    time_t t;
    unsigned long measured_at;
    if (queryNTP("pool.ntp.org", t, measured_at)) {
        setTime(t, millis() - measured_at);

        // Insert whatever you want to with the received time here

        // run again in an hour
        UTC.setEvent(timeSyncEvent, now() + 3600;
    } else {
        UTC.setEvent(timeSyncEvent, now() + 5;
    }
}

 

I do plan for some future version to make the time updates such that time only goes forward (monotonous time) and corrections are done by adding or subtracting a few milliseconds here or there.

I'll also think about how to support RTC clocks, GPS receivers and the like.

Thanks for the ideas, excellent software library.
