[HTTP measurements] Units of timing?
When using "extended_timing" with HTTP measurements, in what units are tt*? I suspect that ttr is in seconds and the other two in milli-seconds but I want to be sure. (The Web interface does not display these values, it seems, but see measurement #74293060 if you want an example.)
Hello again, According to the documentation (https://atlas.ripe.net/docs/apis/result-format/#version-5000) those fields are in milliseconds. I believe this to be correct; your referenced measurement uses resolve-on-probe: false, therefore the DNS resolution is done at specification time and it's a no-op on the probe.

Yes, thanks. (But NTP measurements are in seconds, so I'll remember to read the documentation.)

Thanks, I forgot this important thing. I'll remember.
