How Does the Go Time Format '2006-01-02' Work?

Understanding the Time Format '2006-01-02' in Go

In Go, the time.Format function allows you to format a time.Time value using a custom layout. While the documentation mentions that any layout can be used, there are specific guidelines for creating the layout string.

The reference time format, "Jan 2 15:04:05 2006 MST," helps understand the meaning of each section of the layout string. Let's break it down:

• 1: Year, as a decimal number (00-99).
• 2: Month, as a decimal number (01-12).
• 3: Day of the month, as a decimal number (01-31).
• 4: Hour (0-23) in 24-hour format.
• 5: Minute (00-59).
• 6: Second (00-59).
• -7: Time zone abbreviation or offset (e.g., "MST" or " 0800").

Therefore, the layout string '2006-01-02' corresponds to the following sections of the reference time: year (2006), month (01), and day (02). This layout will print the year, month, and day of the time.Time value. Other layouts, such as '2006-10-10' or '1999-02-02,' will also print the year, month, and day, but in different orderings or number of digits.

Remember, the layout string should represent the reference time format to ensure accurate parsing and formatting. For further details, refer to the Go documentation on the Time and Format functions.
