Some problems about the code

[Billiant0203]

There are some bugs when we run your code. We run the codes which were in the file--urine-output-infect-time.sql. And it reported that there are not any information of 'ie.si_starttime' and 'ie.si_endtime'. And then I had read the code in the file named 'suspicion-of-infection.sql'. Definitely, the code didn't create the value of 'si_starttime' and 'si_endtime'. I think something may be wrong in your code. That is our puzzle and we are looking forward to hearing from you. Thank you！
