# 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.
# EXAMPLES
$ date; bup tick; date
Sat Feb 6 16:59:58 EST 2010
Sat Feb 6 16:59:59 EST 2010
# BUP
Part of the `bup`(1) suite.
