bup-tick - wait for up to one second
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.
