Minor simplification of timepicker.timezoneAdjust(). Left the addition of the negation of date.getTimezoneOffset() to make it clear that we need to reverse its sense. Just representing it as straight subtraction might be mathematically simpler and marginally more performant, but would fail to suggest this important detail.
