# 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
