The "set_time_now()" operation is unsynchronized--it simply transfers the host time to the device(s) without any hardware synchronization pulse. Since it necessarily has to send multiple commands across the host-to-device interface, and the device sets its clock immediately to whatever value is provided, and the clock continues to run, then two or more devices will not tightly agree on the time when using this method.
The issue is that there is only one device. With "set_time_now()", two daughterboards on the same device (same motherboard) behave as unsynchronized.
