Hi All,
I am recording data with OpenBCI Cyton board (Cyton + Daisy). I have enabled logs for SD Card.

In the PC log I could see the time stamp, but in SD Card I could not get time stamps.

Is it possible to get the time stamp (UTC) in SD Card log? , and if yes:
How to enable the time stamp (UTC) in SD Card log ?

Regards,
Pluto.

    Pluto, hi.

    The Cyton board firmware does not contain an updated, real-time, microsecond-resolution, UTC clock. Any timestamps you see in the OpenBCI_GUI recording CSV file, were assigned as the samples were received at the laptop. They reflect the clock in the laptop at reception time.

    Thus there is no way to record timestamps on the SD card.
