We use Universal Time for all of our observations. There is 10 hours difference between UT and HST (Hawaiian Standard Time). We do not use Daylight Saving Time in Hawaii.
Therefore, midnight in UT occurs at 2 in the afternoon in Hawaii:
| 8 am in Hawaii | = 1800 UT |
| 12 noon | = 2200 UT |
| 2 pm | = 0000 UT |
| 5 pm | = 0300 UT |
| 10 pm | = 0800 UT |
| 12 midnight | = 1000 UT |
