Calendar Date of Connection?

Is there some way to determine the calendar date of a connection? I see I managed to deliver a VMail straight to the intended recipient when the operator connected to my station; scrolling up through the activity log/chat screen I can discern a UTC time, but I don't know what day it was. Even more interesting, I had my beacon turned off, so the station must have just attempted a connection with me on the chance that my station was listening on the frequency, which it was.
