Mass Update 'all day Calendar events

There is an issue with the calendar reminders, that is when you have an ‘all day event’ then the device would wake up at 12:00 AM to remind you. For some people it might be ok but most of us want device to show the reminder at some convenient time (such as 08:00 AM when having a coffee).

Here is the possible fix(There might be other solutions too which I am not aware of)
This is a small utility I built which will allow you to mass update all such events to some fixed time span. That is converting all these all day events to non all day with the option to set your own time span.
