"(new Date).zeroTime is not a function".
jQuery DatePicker JS Error.
One of my developers recently encountered a jquery issue. He tried to use the jquery DatePicker.js and for some reason (this error) couldn't make it work.
When he tried to open the DatePicker.js calendar he got the error: "(new Date).zeroTime is not a function".
This error happens because the function "zeroTime" is not being added to the data prototype. it should be added in the date.js file, which was not updated.
After updating the date.js (available here) it all went smooth.
Hope it helped,
