This value is now referenced in two places that need to remain in sync, should we ever decide to change it. Let's make a constant for it.

if let Some(current_dt) = datetime {
use esp_idf_svc::sys::{settimeofday, timeval};
let tz = chrono_tz::Tz::UTC;
std::env::set_var("TZ", tz.name());

  • We probably should only be doing the env var set once, at startup. Also not clear to me that it is safe for us to be calling it at all, as an MT program:
In multi-threaded programs on other operating systems, the only safe option is to not use set_var or remove_var at all.

let tv_sec = current_dt.timestamp() as i32;
let tv_usec = current_dt.timestamp_subsec_micros() as i32;
let current_timeval = timeval { tv_sec, tv_usec };
let res = unsafe {

You don't really need res right?

if unsafe {...} != 0 { log::error!... ought to do

or the esp! macro to convert it to a result

settimeofday(&current_timeval as *const timeval, std::ptr::null())
};
if res != 0 {
log::error!(
"could not set time of day for timezone {:?} and timestamp {:?}",
tz.name(),
current_dt
);
}
}

Fine to defer this into a new ticket, but should we consider calling adjtime if we have a good local datetime but it differs from what app is telling us?

Is this right? I think the idea of returning out of run here is that if you didn't have enough info to calculate timestamps now, why would you move on to the next collector, which will just fail the same way? Instead, bail out of run and hope that the next time run is queued up by invoke that the situation has improved. As written with continue, won't this just result in the repeated logging of Could not calculate data timestamps, returning without flushing store, once for each configured collector, and then returning anyway?
