GPS UTC timing #501

Open tnk3r opened 8 years ago

tnk3r commented 8 years ago

How can I call the UTC time with dronekit? I can't seem to find any documentation about it.

hamishwillee commented 8 years ago

@tnk3r What is it you are actually trying to do? There is no API to get current UTC time in dronekit itself, but plenty of APIs in Python.

tnk3r commented 8 years ago

Right, I am looking at pymavlink.

I am trying to sync multiple pixhawk together for timing and triggering actions. One obvious reason is syncing air and ground vehicle cameras with streaming cameras. They can easily be synced by providing initial timestamp when opening video stream. Then calculating offsets from one another.

@tnk3r We don't directly expose any timestamp information like that in DroneKit. However if there is a MAVLink message that is sent by the autopilot with this information you can intercept it in your dronekit app as described here: http://python.dronekit.io/examples/create_attribute.html

Interesting, I'll give it a test. I'll report back soon.

Thanks. If you work out a good message and approach for synchronization we can add this to the API.

Having a simple function to set companion board date and time from GPS would also be useful - otherwise your times in logs are off.
