Fix bugs in our internal hours tracker app

We have an basic php app which communicates with the freshdesk api ([login to view URL]) to allow us to login into the app, list tickets and add notes and track time. The current app has 2 ongoing bugs that have frustrated staff that we need to address asap. - The code fundamentally seems to be not parsing the json it receives correctly, on logon to the app, it displays the dates of the tickets (which show the current month January as 00 rather than 01), results repeat themselves down the page, i.e. duplicate results. - When we press one of the buttons to add time/notes to a job, almost always we get an error "requester not available"which is a command the API returns indicating the client that submitted the ticket doesn't exist, but when you check freshdesk they clearly do, again, the code isn't parsing the customer ID correctly. These are the primary issues, there are 2 other minor errors we've encountered but aren't a high priority and can be easily fixed.
