How Do I Convert Go's `time.Time` to Custom String Formats for Database Storage?

Convert Time Formats for Database Population

When manipulating data from a database, it's often necessary to convert time values to strings. This conversion is crucial when storing values in a slice of strings. Go offers a convenient solution for this task.

Time to String Conversion

Go's time.Time type represents timestamps. To convert a time.Time value to a string, use the Time.String() method. This method formats the timestamp according to the predefined layout string: "2006-01-02 15:04:05.999999999 -0700 MST."

Custom Date Format

If you require a more specific date format, you can use the Time.Format() method. This method takes a layout string that defines the desired output format. For instance, to format a timestamp as "yyyy-MM-dd HH:mm:ss," use the layout string "2006-01-02 15:04:05."

Usage Example

Consider the example code provided:

t := time.Now()
fmt.Println(t.String())
fmt.Println(t.Format("2006-01-02 15:04:05"))

Output

2009-11-10 23:00:00 +0000 UTC
2009-11-10 23:00:00

Note:

• The output time on the Go Playground is always fixed. Run the code locally to see current date/time.
• Time.Format() requires a reference time (in a specific predefined format) to determine the desired output format.
