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
