NAME

       bup-tick - wait for up to one second

SYNOPSIS

       bup tick

DESCRIPTION

       bup tick  waits  until  time(2)  returns  a  different  value  than  it
       originally did.  Since time() has a granularity of one second, this can
       cause a delay of up to one second.

       This  program  is  useful  for writing tests that need to ensure a file
       date will be seen as modified.  It is  slightly  better  than  sleep(1)
       since it sometimes waits for less than one second.

EXAMPLE

             $ date; bup tick; date
             Sat Feb  6 16:59:58 EST 2010
             Sat Feb  6 16:59:59 EST 2010
