If the initial mass is too great, the pasteurization temperature may not be achieved before the solar flux becomes too low. Then, considering that the hour angle at local solar noon is 0°, with each 15° of longitude equivalent to 1 h, the sunrise and sunset time in hours from local solar noon is then 6.68 h. In consequence, the sunrise is at 5.32 (5:19:12 in h:m:s format) and the sunset at 18.68 (18:40:48), being the day length 13.36 h (13:21:36).
