-/**
- * The time zone used for performing astronomical computations for
- * Dangi calendar. In Korea various timezones have been used historically
- * (cf. http://www.math.snu.ac.kr/~kye/others/lunar.html):
- *
- * - 1908/04/01: GMT+8
- * 1908/04/01 - 1911/12/31: GMT+8.5
- * 1912/01/01 - 1954/03/20: GMT+9
- * 1954/03/21 - 1961/08/09: GMT+8.5
- * 1961/08/10 - : GMT+9
- *
- * Note that, in 1908-1911, the government did not apply the timezone change
- * but used GMT+8. In addition, 1954-1961's timezone change does not affect
- * the lunar date calculation. Therefore, the following simpler rule works:
- *
- * -1911: GMT+8
- * 1912-: GMT+9
- *
- * Unfortunately, our astronomer's approximation doesn't agree with the
- * references (http://www.math.snu.ac.kr/~kye/others/lunar.html and
- * http://astro.kasi.re.kr/Life/ConvertSolarLunarForm.aspx?MenuID=115)
- * in 1897/7/30. So the following ad hoc fix is used here:
- *
- * -1896: GMT+8
- * 1897: GMT+7
- * 1898-1911: GMT+8
- * 1912- : GMT+9
