I see, that's interesting Grand DM. AFIK, that does not currently exist for Roll20 yet, never seen anyone do it inside Roll20. Of course you could use your own stopwatch at home, or even point a Roll20 camera at a clock. I'm skeptical of the Animated GIF method for this. There are 2-minute animated GIF countdown clocks in Roll20 Marketplace. Have not seen 60-minutes. I'm skeptical about whether it would actually match real-time or just be a countdown that doesn't necessarily count-down 1 per second. The longer it goes, the more "off" it could become. It might stay on steady realtime but I have doubts (about how fast different web browsers or computers might play-back a GIF frame by frame, and if there is lag or skipping). So a working question here is, does your game matter if 60 minutes is really 60 minutes exactly, or would be OK if the 60-minute countdown seemed to take longer or shorter to reach 0:00? Look into what The Aaron said, he's probably right about the API Mod of Roll20 being able to accomplish this. As a Roll20 Pro you could ask this question again, under the API Mods sub-forum.
