I have been testing out the Particle monitor command. I came across --time.
particle monitor <My device id> analogvalue 5000 --time
This appears to be the current time that it was read. But which time? The particle device or my PC?
I am thinking time zones here. It doesn’t appear to be GMT. I checked the documentation no help there Particle monitor
I am just curious.
I’d say it’s the computer time since I’m unaware of the Photon sending the time if not explicitly instructed to.
On the other hand there would be a third (less likely) option - the cloud time.
And since you seem to be in Denmark the
+02:00 would fit your time zone - GMT+1 +1h DST.
You could also check if it was the devices time by setting
yeah my guess was it was computer time as well. I suppose i could spin up a VM in a different timezone and we can test it
I’d see reflashing the Photon as the easier way
And the cloud time woud be UTC (+00:00 or Z)
Ohh didn’t know you can do that. Awesome idea.
If you don’t set
Time.zone() in your code it will be assumed as +0 (=UTC)
See now I would assume it would get the time from the WiFi. BTW I don’t need this i just suffer from the disease of rampant curiosity.
I am waiting for more stuff to come in the mail so in the mean time i have to do with it what I can.
Nope, the RTC is initially synced to UTC when first connected to the cloud (or later when it drifts by you via
It’s up to you to set the zone and also care for DST offsets (via
currenttime = Time.now();
Particle.variable("currenttime", ¤ttime, STRING);

Anwser: --Time is the local time on the machine running the request.
