runwhen is a set of utilities for running commands at particular times. With these tools, you can perform calculations on time values in various ways, and use those calculated times to determine how long a process should sleep before performing some task.
This package is discussed on the prjware list. New releases are announced on the prjware-announce list.
runwhen is devoid of warranty and is distributed under the GNU General Public License, version 2. But that doesn't mean it's necessarily a good idea for you to distribute modified versions. (That includes repackaging.) I'd like to know if you plan to do that.
Older versions are published for historical interest.
You can get the latest development sources with:
$ git clone git://git.dogmap.org/runwhen.git
To build runwhen, you need Laurent Bercot's
conf-compile/depend_* as necessary during installation.
Aside from the obsolete commands, runwhen is believed to work with both TAI
clocks and POSIX clocks. (TAI-clock systems should use a
time zone and have
/etc/leapsecs.dat; POSIX-clock systems
should use a non-
right/ time zone and have no

rw-sleepprogram sleeps until a given time and executes a given command.
rw-addprogram computes the sum of two timestamps.
rw-subprogram computes the difference of two timestamps.
rw-minprogram computes the smaller of two timestamps.
rw-maxprogram computes the larger of two timestamps.
rw-matchprogram computes a timestamp matching given constraints.
rw-touchprogram updates a file's last-modified time.
