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
