PHP Emergency fix - MUST be available right now

I have something simple that needs fixed: On the page called "[login to view URL]" I need a couple things. I will explain what this page does: It tracks the users that are currently listening to our audio stream "LIVE", the problem is that if a user logs in and out several times throughout the hour, every time they are logged in, it counts them as anew user. So if one user logs in 5 times, then it reports that there are 5 users logged in that hour, even though there is only one. So i need that fixed. Also I need the user that is logged in to be grouped with its own iformation instead of having a line for each. What i mean by this, is currently if a user signs in at 10:05, then signs out at 10:07, then signs back in at 10:15, then out at 10:19, then back in at 10:30, etc. I need all the times within the hour to be grouped for each user. I also need the time to be reported in EASTERN TIME ZONE. Currently im not sure how its being reported, but if i look at this page, it shows users logged in for 5 hours from now in the future. I need this to be logging the times in EST. Lastly, i need the column to report "Listener" in the first column instead of "Email" for the header of the column, and also if the email is null in the database, then it should display their UDID (from the UDID field in database) instead as data for that display field. Whatever you bid will be the amount you will be paid for this project if accepted. So if you ask "what is your budget" then the conversation will be terminated since i will know that you didnt read this description and blindly bid. My time is very valuable so I need to be productive and make sure that i am only talking to qualified candidates. Please PING ME when you are ready to begin, so that I can answer and questions. You will not be given any kind of access to the server without being monitored, all files will be sent to me, for upload, no cpanel access or myphp access or database will be provided, but if chosen for this project, i will send you the url to view the live real time data. All source code files are attached. Please review them BEFORE you message me. Payment will be released once we have verified the project to be working 100%. Thank you, and good luck!
