I’m currently working as an operations engineer at a national science facility. Naturally all of our data and systems use UTC time… NOT, so I need to quickly convert MST to/from UTC pretty much all day long. My original plan was a pair of clocks with the two time zones, but I share a small office with almost zero wall space.
Glowforge to the rescue! I just built a clock out of Draftboard featuring a rotating outer bezel that indicates UTC. Since the delta is always 6 or 7 hours (stupid DST…), the bezel allows just enough travel to adjust it twice a year.
This will eventually be made out of a finished wood, tbd, with properly-sized hands, but as you’ll see below the draftboard worked perfectly, allowing me to make notes and registration marks as I modified the design on the fly.
Bonus points if you can figure where PG saved the day…
