If it's noon in Greenwich (0 degrees longitude), then at 60 degrees east, it would be 3:00 PM. This is because the Earth is divided into 24 time zones, each representing 15 degrees of longitude, meaning each hour corresponds to 15 degrees. Thus, 60 degrees east is four hours ahead of Greenwich Mean Time (GMT).
If it is 12 noon at Greenwich (0 degrees longitude), then every 15 degrees of longitude corresponds to a one-hour time difference. Therefore, if you are 30 degrees east of Greenwich, the time would be 2:00 PM.

Greenwich Mean Time (GMT) is the time at the Prime Meridian, which is 0 degrees longitude. Tokyo, located at 140 degrees east, is 9 hours ahead of GMT. Therefore, when it is 12 noon on Monday at Greenwich, it would be 9:00 PM on Monday in Tokyo.
Greenwich Mean Time (GMT) is the time at the Prime Meridian (0 degrees longitude). Each degree of longitude corresponds to a time difference of 4 minutes. At 20 degrees east longitude, the time would be 20 degrees × 4 minutes = 80 minutes ahead of GMT. Therefore, if it is 12 noon at Greenwich, the time at 20 degrees longitude would be 1:20 PM.
When it is 12 noon at Greenwich (0 degrees longitude), it is 20 degrees west of Greenwich. Since the Earth rotates at 15 degrees per hour, you can calculate the time difference by dividing 20 degrees by 15, which equals approximately 1 hour and 20 minutes. Therefore, it would be 10:40 AM at the location that is 20 degrees west when it is 12 noon at Greenwich.
If it is 12 noon at Greenwich (0 degrees longitude), then every 15 degrees of longitude corresponds to a one-hour time difference. Therefore, if you are 30 degrees east of Greenwich, the time would be 2:00 PM.

England's Royal Observatory in Greenwich (the source of Greenwich Mean Time - GMT) is 0 degrees longitude and the reference point. 120 degrees East is the longitude of the east coast of Taiwan. At that longitude, 1/3 of a circumference from Greenwich, the standard time (and date) should be 8 hours ahead of Greenwich. So if it is 4am in Greenwich, it should be noon in Taiwan.
Greenwich Mean Time (GMT) is the time at the Prime Meridian (0 degrees longitude). Each degree of longitude corresponds to a time difference of 4 minutes. At 20 degrees east longitude, the time would be 20 degrees × 4 minutes = 80 minutes ahead of GMT. Therefore, if it is 12 noon at Greenwich, the time at 20 degrees longitude would be 1:20 PM.
Greenwich (England) is at (Greenwich Mean Time) GMT. Paris is (Greenwich Mean Time) GMT +1 hours, ie. 1 hours ahead of Greenwich, England. At noon in Greenwich, England, it is 1 pm in Paris. (Daylight savings not taken into account.)
The time zones of the world are set according to Greenwich Mean Time, from the Greenwich Observatory in England. If it is noon in Japan, it is 0300 or 3 o'clock in the morning in Greenwich.

Singapore's time is 8 hours ahead of GMT (GMT +8); noon in greenwich would equate to 8pm in Singapore.
Houston is in the Central Time Zone, which is 6 hours behind Greenwich Mean Time. Therefore, if it is 12 noon in Greenwich, it would be 6 AM in Houston.
70W is 180 degrees away from 110E, so if it's noon at 70W, it's midnight at 110E.
