The new-leapsecs command

The new-leapsecs command is a Python script that reads the leap-seconds.list file from, or from a file named on the command line, and outputs a leapsecs.dat file.

The clockspeed-nonroot patch

The clockspeed-nonroot patch prevents clockspeed from installing its own leapsecs.dat file in /etc. This is useful for installing clockspeed as a non-root user or when the existing /etc/leapsecs.dat file is more up-to-date than the one in clockspeed.
