Time

This Go code demonstrates working with the time package to handle dates and times. Let's go through the code with inline comments and explanations:
// Importing necessary packages.
import (
"fmt"
"time"
)
​
// The main function, where the execution of the program begins.
func main() {
// Creating an alias for fmt.Println for brevity.
p := fmt.Println
​
// Getting the current time.
now := time.Now()
p(now)
​
// Creating a specific date and time.
then := time.Date(
2009, 11, 17, 20, 34, 58, 651387237, time.UTC)
p(then)
​
// Extracting various components of the time.
p(then.Year())
p(then.Month())
p(then.Day())
p(then.Hour())
p(then.Minute())
p(then.Second())
p(then.Nanosecond())
p(then.Location())
​
// Determining the weekday.
p(then.Weekday())
​
// Comparing two times.
p(then.Before(now))
p(then.After(now))
p(then.Equal(now))
​
// Calculating the time difference.
diff := now.Sub(then)
p(diff)
​
// Extracting components of the time difference.
p(diff.Hours())
p(diff.Minutes())
p(diff.Seconds())
p(diff.Nanoseconds())
​
// Adding and subtracting time durations.
p(then.Add(diff))
p(then.Add(-diff))
}

Explanation:
  1. 1.
    Getting Current Time:
    • time.Now() returns the current time.
  2. 2.
    Creating Specific Time:
    • time.Date() is used to create a specific date and time.
  3. 3.
    Extracting Components:
    • Various methods (Year(), Month(), Day(), etc.) are used to extract components of the time.
  4. 4.
    Weekday:
    • Weekday() returns the day of the week.
  5. 5.
    Comparing Times:
    • Before(), After(), and Equal() methods are used to compare times.
  6. 6.
    Time Difference:
    • Sub() calculates the time difference between two times.
  7. 7.
    Extracting Components of Time Difference:
    • Methods like Hours(), Minutes(), Seconds(), and Nanoseconds() are used to extract components of the time difference.
  8. 8.
    Adding and Subtracting Time Durations:
    • Add() is used to add or subtract a time duration.
This code provides a basic overview of working with dates and times in Go using the time package. It covers creating, manipulating, comparing times, and calculating time differences.
