bug: timepicker in absolute/since mode reverts date to previous day

[tmkujala]

When selecting a date in the time picker in absolute or since mode, after applying the newly selected date by clicking the check mark button, the date is changed to the previous day.

Steps to reproduce:

1. Open a dashboard that has a time picker on it (http://demo.kibana.org/#/dashboard)
2. Switch to absolute or since mode
3. Select a new date
4. Click the check mark button to apply the new date
5. Watch the date change from your selection to the previous day

Think I found the problem. The datepicker returns a Date in UTC where it's assumed to be local.

I ran into this today. The behavior seems to change depending on what's selected as your 'relative' time when you switch to 'absolute' and enter a range. When I have relative set to 24 hours, then switch to absolute and enter a range for the first 15 minutes of the current day, the first range selection field reverts back a day. When I have relative set to 15 minutes, then switch to absolute and again select the first 15 minutes of the current day, it works correctly.

This is fixed in the new timepicker
