microfortnight n.
1/1000000 of the fundamental unit of time in the
Furlong/Firkin/Fortnight system of measurement; 1.2096 sec. (A
furlong is 1/8th of a mile; a firkin is 1/4th of a barrel; the
mass unit of the system is taken to be a firkin of water). The
VMS operating system has a lot of tuning parameters that you can
set with the SYSGEN utility, and one of these is TIMEPROMPTWAIT,
the time the system will wait for an operator to set the correct
date and time at boot if it realizes that the current value is
bogus. This time is specified in microfortnights!
Multiple uses of the millifortnight (about 20 minutes) and
nanofortnight have also been
reported.
