In the hwclock man page, this section: ... --version Print the version of hwclock on Standard Output. You need the following option if you specify --set option. Otherwise, it is ignored. --date=date_string ... Needs some kind of break before the "You need...". More than just a paragraph break actually. It needs to shift left some too.
The man page displayed fine in util-linux-2.8-11 on a freshly installed 5.2 box.
