How to Convert a String to a Go Time Object with Custom Formatting?

Converting a String to a Go Time Object with Custom Formatting

In Go, you can conveniently parse a string as a time.Time value using the Parse function. However, when dealing with unique time formats not listed in the standard time format package, it's important to define a custom layout string to specify the expected format.

To address your specific question, the given string "20171023T183552" adheres to the format "YYYYMMDDTHHmmSS". Therefore, you can utilize the following code:

s := "20171023T183552"
t, err := time.Parse("20060102T150405", s)
fmt.Println(t, err)

This code defines the layout string "20060102T150405", which corresponds to the format of the input string. By passing this layout to time.Parse, you specify how to interpret the string's characters to create a valid time.Time value.

The result of parsing the time string is a time.Time object representing the date and time in the given format, and a nil error indicating successful parsing.

Note that this approach is applicable to any non-standard time format you encounter. By defining a custom layout string, you can parse the string into a time.Time object, allowing you to manipulate and compare time values effectively in your Go code.
