During review for bug 5061412, it was noted that the composite date/time
suffix 'r' references the now deleted suffix 'P'.
The review comment describes the problem very clearly:
"%tP" should be "%Tp" in the following 'r' descriptions.
478 * <tr><td valign="top"><tt>'r'</tt>
479 * <td> Time formatted for the 12-hour clock as <tt>"%tI:%tM:%tS %tP"</tt>.
480 * The location of the morning or afternoon marker (<tt>'%tP'</tt>) may be
481 * locale-dependent.
1651 * <tr><td valign="top"><tt>'r'</tt>
1652 * <td valign="top"> <tt>'\u0072'</tt>
1653 * <td> Time formatted for the 12-hour clock as <tt>"%tI:%tM:%tS
1654 * %tP"</tt>. The location of the morning or afternoon marker
1655 * (<tt>'%tP'</tt>) may be locale-dependent
