请高手帮忙：通道信分时主图如何显示“秒”

分时主图公式只能显示到分钟，我想增加到秒，我在分时后面增加秒钟的代码“second”,但显示失败。请哪位兄指导一下：

D1:=1;
AA1:=STRCAT(CON2STR(YEAR,0),‘年‘);
AA2:=STRCAT(CON2STR(MONTH,0),‘月‘);
AA3:=STRCAT(CON2STR(DAY,0),‘日‘);
AA4:=STRCAT(‘‘,IF(WEEKDAY=1,‘一‘,IF(WEEKDAY=2,‘二‘,IF(WEEKDAY=3,‘三‘,IF(WEEKDAY=4,‘四‘,IF(WEEKDAY=5,‘五‘,IF(WEEKDAY=6,‘六‘,‘日‘)))))));
AA5:=STRCAT(STRCAT(STRCAT(AA1,AA2),STRCAT(AA3,AA4)),‘‘);
AA6:=STRCAT(STRCAT(CON2STR(HOUR,0),‘时‘),STRCAT(CON2STR(MINUTE,0),‘分钟‘));
AA7:=STRCAT(AA5,AA6);
DRAWTEXT_FIX(D1=1,0,0.02,0,AA7),COLORMAGENTA;

我在AA6原文增加秒测试不行。增加修改后的代码如下：

AA6:=STRCAT(STRCAT(STRCAT(CON2STR(HOUR,0),‘时‘),STRCAT(CON2STR(MINUTE,0),‘分钟‘),STRCAT(CON2STR(second,0),‘秒‘));
