fix: error with time-picker when allowInput is true

[zeezo887]

Description

The error occurs because the parseDate function cannot return a valid date for a time string e.g 12:00 AM. The change introduced in this PR appends the time to the current date string so that the function can return a valid date.

if (self.isValidTime(date)) {
  const currentDate = new Date();
  date = `${currentDate.toDateString()} ${date}`;
}
