Hello Guido,
The B-Station does not have a built in clock. Which prevents it from triggering a cue on a specific time and date on its own.
However the B-Station can be triggered using UDP or OSC messages. If you have a device which does have a clock and is able to send UDP or OSC messages. You can trigger a cue in the B-Station using a UDP or OSC message.
I hope this helps you.
Best regards,
Guido
