Is a jiffy a 1/100th second?
The term "jiffy" is sometimes used in computer animation as a method of defining playback rate, with the delay interval between individual frames specified in 1/100th-of-a-second (10 ms) jiffies.
This is a response last updated by Terry on Sep 23 2016.Apr 18, 2002 to the following question: "Is a jiffy an actual unit of time? As in "be there in a jiffy ..."
Jiffy is an informal term for any unspecified short period, as in "I will be back in a jiffy." From this it has acquired a number of more precise applications for short, very short, extremely short, ultra short or hyper short periods of time.
The earliest technical usage for jiffy was defined by Gilbert Newton Lewis (1875–1946). He proposed a unit of time called the "jiffy" which was equal to the time it takes light to travel one centimeter in a vacuum (approximately 33.3564 picoseconds). It has since been redefined for different measurements depending on the field of study ...
The term "jiffy" is sometimes used in computer animation as a method of defining playback rate, with the delay interval between individual frames specified in 1/100th-of-a-second (10 ms) jiffies, particularly in Autodesk Animator .FLI sequences (one global frame frequency setting) and animated Compuserve .GIF images (each frame having an individually defined display time measured in 1/100 s).
Since I am neither a physicist nor a computer animator, I will be sticking with "jiffy" as a "very short period of time." However, it's nice to know that this general statement has now precipitated into some very specific measuring tools, when needed for "more precise applications."
Like I said, I am willing to take knowledge where I find it. Even inside a bottle cap!
