In a Jiffy...
Caught myself using this phrase tonight "i'll be there in a jiffy" , and I got to wondering, exactly how long is a Jiffy... I certainly do not want to be late... Maybe I really need TWO Jiffy's worth of time to get there 
How long is a Jiffy?

Actually, "jiffy" is a technical term defined as different things in different applications.
In electronics, a jiffy is the time between alternating current power cycles (1/60 or 1/50 of a second).
In computing, a jiffy is the duration of one tick of the system timer interrupt. It is not an absolute time interval unit, since its duration depends on the clock interrupt frequency of the particular hardware platform. Typically, this time is 0.01 seconds; on early microcomputer systems and on many game consoles (which use televisions as a display device), it is common to synchronize the system clock with the vertical frequency of the local television standard (either 59.94 Hz with NTSC systems, or 50.0 Hz with most PAL systems). Within the Linux 2.6 operating system kernel, since 2.6.13 release, on the Intel i386 platform, a jiffy is by default 4 ms, or 1/250th of a second. The value for older Linux 2.6 kernels (up to 2.6.12), on same platform, is 1 ms, or 1/1000th of a second.
In physics (particularly in quantum physics and often in chemistry), a jiffy is the time taken for light to travel the radius of an electron. Sometimes a jiffy is defined as the time taken for light to travel one foot, or sometimes the width of a nucleon in a vacuum.
A jiffy in astrophysics and quantum physics, as defined by Edward R. Harris, is the amount of time it takes for light to travel one fermi (the size of a nucleon). One fermi is about 10^-13 cm, so a jiffy is equal to 10^-23 seconds. In the article, it is noted that the name was suggested for this unit by Richard Tolman.

It's a defined duration of time shorter than what the human brain can actually discern, so by saying "be there in a jiffy" you are using a tired old hyperbole that implies whatever you think it does.
