![]() ![]() At one point, train stations in the United States alone had to keep up with 75 time zones across the country. Especially as people began to travel across North America by train, the many time zones became difficult to follow. Then, they would go around town and adjust other people’s clocks to make sure they matched.Īs the world became more connected, this grew complicated. One person would make sure the official town clock read noon when the sun was highest in the sky each day. Just over a century ago, towns and cities set their own time. People have lived in different time zones for a long time, but it hasn’t always been as organized as it is today. Since different parts of Earth enter and exit daylight at different times, we need different time zones. Noon would be the middle of the day in some places, but it would be morning, evening, and the middle of the night in others. Imagine if the entire Earth had a single time zone. When your location rotates out of sunlight, you see the sun set. As your location on Earth rotates into sunlight, you see the sun rise. As Earth rotates, different parts of Earth receive sunlight or darkness, giving us day and night. Every 24 hours, the Earth makes a complete rotation. You know our planet is a sphere that spins on an imaginary pole called its axis. To understand time zones, start by thinking about the shape of the Earth. How is that possible? Is it time travel? Of course not! They just live in a different time zone. What time is it where you are? Have you ever traveled to another place and experienced a time change? Maybe you know someone who lives far away and is a few hours ahead of you. The t1 variable is the current time in UTC, and the t2 variable is the current time in the "America/New_York" time zone.Quick, find the nearest clock. In the main function, the Zone method measures the duration of the time zone shift between two time zones (time.Time values). " between UTC and New York is: %d seconds", duration) Calculate the duration of the time zone shiftįmt.Printf( "The time zone shift duration" + Get the offset in seconds for each time zone Get the current time in UTC and the specified location Loc, err := time.LoadLocation( "America/New_York")įmt.Println( "Error loading location:", err) Load the time zone location for America/New_York "EST" for "America/New_York") and an integer representing the number of seconds east of the UTC. The Zone method returns the string representing the abbreviation of the time zone (e.g. The time package provides the Zone method for retrieving the abbreviation and offset of the time zone associated with a time.Time value. Many methods use the Time and Location structs, including the time zone methods. ![]() range defined by cacheStart and cacheEnd. cacheZone points to the zone that is currently valid for the time for which the cacheZone field is valid. cacheStart and cacheEnd are Unix timestamps that deine the range extend contains the name of a parent time zone if this location tx contains information about when the time zone abbreviation or and rule for a single time zone in the location. zone contains information about the time zone abbreviation, offset, name is the time zone name, such as "UTC" or "PST". loc is a pointer to the Location struct associated with this time. ext is the monotonic clock reading in the format returned by wall is the wall time in the format returned by the runtime.nanotime() The fields are unexported, so they’re absent from the official documentation. Here’s the time struct type and its fields. You can import the time package with an import statement. The time package provides a Time struct type containing the location field you can use to set time zones. The time package provides functionality for working with times and dates, measuring and displaying time, and manipulating dates using a Gregorian calendar without leap seconds. ![]()
