 We present here a few built-in registers that are not described
 elsewhere in this manual; they have to do with invariant properties of
 GNU @code{troff}, or obtain information about the formatter's
-command-line options or the operating environment.  Date- and
-time-related registers are set per the local time as determined by
-@cite{localtime@r{(3)}} when the formatter launches.  This
-initialization can be overridden by @env{SOURCE_DATE_EPOCH} and
-@env{TZ}; see @ref{Environment}.
