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.
Noon Greenwich Mean Time in Greenwich (UTC/UTC+1) = 2 PM Eastern European Time in Kiev (UTC+2/UTC+3) 1 PM British Summer Time in Greenwich = 3 PM Eastern European Summer Time in Kiev
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.
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 in New York City, it would be 5 pm in Greenwich, England. Greenwich Mean Time (GMT) is typically 5 hours ahead of Eastern Standard Time (EST), which is the time zone New York City is in.
When it's 12 noon NDT on Newfoundland Island, it's 2:30 PM GMT. When it's 12 noon NST on Newfoundland Island, it's 3:30 PM GMT.
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.
4 AM. San Francisco is eight hours behind.
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.
