The reflects on the time of reload having finished. This is the time when the data is actually swapped in the application. From your example this simply means that your reload takes 30 minutes to execute.
Yes I know it will reflect the finished time and I have mentioned the reload task finished by "09:00". The mentioned task started by 08:53 and it took 7 minutes and the reload is finished by 09:00. But the "Data Last Loaded" part shows 09:30.
