No future date for filtered public share

[mikoladz]

I am trying to add a filtered publicly shared tracking in phonetrack 0.7.6 and it seems it is impossible to add a filter with future date. tsmin (start date) is always set to current day in a link, even if I select something in the future in filters. Because of this it is impossible to prepare and share a link in advance, but instead one has to wait till the day comes.
