For a long time, the Solaris support in chrony wasn't tested on a real Solaris system, but on illumos/OpenIndiana, which was forked from OpenSolaris when it was discontinued in 2010. While Solaris and illumos might have not diverged enough to make a difference for chrony, replace Solaris in the documentation with illumos to make it clear which system is actually supported by the chrony project.
