Initial time element of date time picker

I would like the date/time picker to initialize at 00:00:00 , for example they pick a custom time mm/dd/yyyy 00:00:00

I have hour increments in my data, but normally the view is by day so starts at 00:00:00 and runs through 23:00:00

is there a way to set this to not use current time ? or overide it

Thanks

You can select ‘Today’ in time picker.
or i am not understam to you??

Thanks but that is not really what I am asking . I need the time to be 00:00:00 since my date ranges need to align at the begining of each day. Today if they hit the DATA button, it defaults the time to whatever time it is on my machine.

Once I set it today to 00:00:00 it keeps it, but my users will not remember to set that , so I want to default the time to 00:00:00 no mater what date they select

Thanks
