The allowed %ARGS are string => POSIX strftime string min => minimum time stamp (inclusive) max => maximum time stamp (exclusive) The C and C time stamps must be in the same format as the C supplies. B The algorithm to implement C and C barriers is very simplicistic - it tries as many random values as necessary to meet the two criteria. This means that your script may enter an infinite loop if the criteria can never be attained or are too little apart. =item name [NEWNAME] Gets and sets the name of the HTML field this value corresponds to. =item value FIELD Returns the value to put into the HTML field. =back =head2 EXPORT None by default. =head2 COPYRIGHT AND LICENSE This library is free software; you can redistribute it and/or modify it under the same terms as Perl itself.
