- * Get timezone and daylight saving data

+ * a timestamp in UTC time should result in local time for the current time
+ * zone, and subtracting it from a timestamp in local time should result in
+ * UTC time.

+ * Ideally, this function should satisfy the stipulations applied to LocalTZA

+ *                1970-01-01, a day is exactly 86 400 000 milliseconds, and
+ *                leap seconds cause the same second to occur twice.
+ * @param is_utc Is the given timestamp in UTC time? If false, it is in local
+ *               time.

+ * @return milliseconds between local time and UTC for the given timestamp,
