Timezone Issue: DST cause items on calendar to not show in correct time slot

Bug

What's the current behavior?

If you are going to create an event via the onSelectSlot functionality on Sunday November 4th, 2018 you are going to see a 2 hour offset error. The reason for this is because on November 4th the timezone will change from PDT to PST (daylight savings).

What's the expected behavior?

What is expected is that BigCalendar should automatically detect that on November 4th it should know to adjust from PDT to PST so it does not have a 2 hour offset.

As you can see from the example as I am creating an event right now on Sunday November 4th it will have a 2 hour offset. The calendar is showing my 7AM - 9AM event on the 9AM - 11AM grid.

Seems like this is related to #1028

@quyphan have you seen #1044 and corresponding PR #1046? I tried to run examples with that fix and event time is the same as slot time on the left.

@anna-kartynnik Thanks for fixing this! I showed the before and after in your PR #1046
