This seems like an incredibly dumb question, but I simply don't know the answer. I have a Time-O-Lite P-72 timer (or I think it's that model. It's fairly old and it is what I call the "standard" Time-O-Lite timer in the green/grey metal casing). Anyhow, I have used it for awhile, but realized something recently. Between the "zero" mark and the "60 second" mark is a space that equals about 4 seconds. I never looked, but assumed that as the timer ran down to zero it stopped. My timer goes to the 60 second mark. This means, for example, that if I set the timer for 12 seconds, it actually runs for 16-17 seconds. I figured my timer was broken. So I went to the Adorama website and pulled up a picture of the Time-O-Lite P-72 timer. Lo and behold, the timer in the photo had the needle sitting on the "60 second" mark and not the "zero" mark. Is this right? Are these timers supposed to do this? Any insights? Now, I have always been told that there is no such thing as a stupid question, but now I know that is not true. There CAN be stupid questions, and this one seems pretty stupid. It's just that the answer has me stumped. So I apologize in advance.
