Clock Torture
I now have systems I support in all time zones in the continental United States. Obviously, I can look at my watch and do the math in my head, but there is something efficient about seeing the different time zones at a glance. In my office, I just installed four wall clocks...Eastern, Central, Mountain, and Pacific) from west to east by time zone. I synced them to the minute, but the seconds are just a hair off, so, instead of one click per second, it's 4 unsynchronized clicks per second (and a half). I'm going to have to replace them with clocks with silent sweep second hands of I'll be in the fucking nut-house soon.
I liken this to Chinese Water Torture
