VB 6.0将时、分、秒转换为时间，就是把输入文本框中的内容，重新组合，并添加连接符，形成人们视觉习惯上的时间格式。
其实实现这个功能，不两行代码就可实现了：
Private Sub Command2_Click()
t = TimeSerial(Text1, Text2, Text3)
Label4.Caption = "时间为：" & t
End Sub
SHOW FULL COLUMNS FROM `jrk_downrecords` [ RunTime:0.002551s ]
SELECT `a`.`aid`,`a`.`title`,`a`.`create_time`,`m`.`username` FROM `jrk_downrecords` `a` INNER JOIN `jrk_member` `m` ON `a`.`uid`=`m`.`id` WHERE `a`.`status` = 1 GROUP BY `a`.`aid` ORDER BY `a`.`create_time` DESC LIMIT 10 [ RunTime:0.096119s ]
SHOW FULL COLUMNS FROM `jrk_tagrecords` [ RunTime:0.002570s ]
SELECT * FROM `jrk_tagrecords` WHERE `status` = 1 ORDER BY `num` DESC LIMIT 20 [ RunTime:0.002055s ]
SHOW FULL COLUMNS FROM `jrk_member` [ RunTime:0.002524s ]
SELECT `id`,`username`,`userhead`,`usertime` FROM `jrk_member` WHERE `status` = 1 ORDER BY `usertime` DESC LIMIT 10 [ RunTime:0.003794s ]
SHOW FULL COLUMNS FROM `jrk_searchrecords` [ RunTime:0.002323s ]
SELECT * FROM `jrk_searchrecords` WHERE `status` = 1 ORDER BY `num` DESC LIMIT 5 [ RunTime:0.003276s ]
SELECT aid,title,count(aid) as c FROM `jrk_downrecords` GROUP BY `aid` ORDER BY `c` DESC LIMIT 10 [ RunTime:0.015271s ]
SHOW FULL COLUMNS FROM `jrk_articles` [ RunTime:0.002328s ]
UPDATE `jrk_articles` SET `hits` = 1 WHERE `id` = 290999 [ RunTime:0.001210s ]
