Merge "b/3054044 Make allDay event times format in utc" into gingerbread

         * This formats a date/time range using Calendar's time zone and the

         * local conventions for the region of the device.

         *

         * If the {@link DateUtils#FORMAT_UTC} flag is used it will pass in

         * the UTC time zone instead.

         *

         * @param context the context is required only if the time is shown

         * @param startMillis the start time in UTC milliseconds

         * @param endMillis the end time in UTC milliseconds
