  From  Jargon  File  (4.2.3,  23  NOV  2000)  [jargon]: 
 
  jiffy  n.  1.  The  duration  of  one  tick  of  the  system  clock  on 
  your  computer  (see  {tick}).  Often  one  AC  cycle  time  (1/60  second  in 
  the  U.S.  and  Canada,  1/50  most  other  places),  but  more  recently  1/100 
  sec  has  become  common.  "The  swapper  runs  every  6  jiffies"  means  that 
  the  virtual  memory  management  routine  is  executed  once  for  every  6 
  ticks  of  the  clock,  or  about  ten  times  a  second  2.  Confusingly,  the 
  term  is  sometimes  also  used  for  a  1-millisecond  {wall  time}  interval. 
  3.  Even  more  confusingly,  physicists  semi-jokingly  use  `jiffy'  to  mean 
  the  time  required  for  light  to  travel  one  foot  in  a  vacuum,  which  turns 
  out  to  be  close  to  one  _nanosecond_.  4.  Indeterminate  time  from  a  few 
  seconds  to  forever.  "I'll  do  it  in  a  jiffy"  means  certainly  not  now 
  and  possibly  never  This  is  a  bit  contrary  to  the  more  widespread  use 
  of  the  word  Oppose  {nano}.  See  also  {Real  Soon  Now}.
