Hello,
thanks for your reply, but my question was about the network interface. I would have liked to know how to use the button shown by the black arrow having only one date variable (shown by the green arrow).
We stopped and restarted our systems and it works by itself now without any modification.
What bothered me was that I couldn't configure 'Valid "To" field' under "Dates and Locations" tab, and I thought it prevented the use of the time slider in network view, but it seems to work fine without it (shown by the red arrow), so it's good for me.
Thank you very much
