zoho displays wrong date and problem ocur while insert textbox control using drag & drop in the form

The date of zoho.currentdate shows the wrong date on any day before 12:00 AM after that it shows correct date.
It means before 12:00 AM it shows the date of one ago, and after 12:00 AM it shows correct date.

 What could be the reason for that?
how to solve it?

And another one is i cant insert any single line or multi line textbox control using drag and drop in my form
i don't know whats the problem.
is there any page size limit?
