How to set device prop value ("DateTime")

Hi, i am using python to maintain getting images by Sequoia.
The reason i want to set time in camera, is that after:


I am always getting: 19700101T020423.671363+0000
it seems that timer is starting from 1970 when you power off the camera.

(1) what is the second argument in this setter,

camera.set_device_prop_value(“DateTime”, ?)

(2) how i can just set camera time to system, and not have to think about this never again.
General question - i am looking for document describing all python api. Thank You.

Well, second argument is string also:

camera.set_device_prop_value(“DateTime”, “20190726T133000.000000+0000”)
