The timezone PGT in Papua New GuineaTimezones are always computed by their difference to UTC, the "Universal Time Coordinated". In Papua New Guinea exists only a single tonezone at UTC+10. E.g. New York is currently at UTC-5 in Eastern Time, so the time difference between New York and Papua New Guinea is 15 hours.
Papua New Guinea has no time difference between summer and winter. A daylight saving time doesn't exist.

Papua New Guinea has an east-west extension of 14.4 degrees of longitude. Given the country's location in Melanesia, this corresponds to about 1600 kilometers. With this still relatively small extension, the course of the sun is only slightly different at different positions in the country. The position of the sun in the west of the country differs from that in the east by only about 57 minutes. This means the sun rises and sets 57 minutes later in the west than in the east.
No daylight saving time in Papua New GuineaDue to the sun's orbit around the equator, the days are longer in summer (November to February in the southern hemisphere). Countries that switch to daylight saving time in the summer months align the daylight phase with the human rhythm. Unused bright morning hours are thus shifted into the evening (more information on daylight saving time here).
Due to its proximity to the equator, the impact in Papua New Guinea would not be particularly large. Port Moresby is located just 1,050 km from the equator. A day in midsummer would then not last from 05:48 to 18:31, but from 06:48 to 19:31. The effect would be quite noticeable in the evening, but the sun rising later in the morning falls at a time when many people are already awake. Thus, daylight saving time was never introduced in Papua New Guinea.
