How to convert Datetime to Unix timestamp in Go

🎈 🎈 🎈


    package main

    import (
        "fmt"
        "time"
    )
    
    func main() {
        dateTime := time.Date(1999, 12, 16, 22, 18, 59, time.UTC)
        unixTimestamp := dateTime.Unix()
    
        fmt.Println("Unix Timestamp:", unixTimestamp)
    }

Output:

Unix Timestamp: 945382739

Example only. There may be multiple ways to perform this operation.

Code Explanation

In this Go example, the time.Date() function is used to create a time.Time object representing the specific date and time, eg 2023-10-28 12:44:12.
The Unix() method is then called on this time.Time object to convert it to a Unix timestamp, which represents the number of seconds since the Unix epoch (January 1, 1970). The resulting Unix timestamp, eg 1698499452, is then printed.

Other useful Go date functions

Function	Description	Example
`time.Now()`	Returns the current date and time as a `time.Time` object.	`time.Now()` returns 2024-08-28 12:34:56 +0000 UTC
`time.Date()`	Creates a new `time.Time` object for a specific date and time.	`time.Date(2024, 8, 28, 12, 34, 56, 0, time.UTC)` returns 2024-08-28 12:34:56 +0000 UTC
`time.Unix()`	Converts a Unix timestamp (seconds since epoch) to a `time.Time` object.	`time.Unix(1698499452, 0)` returns 2023-10-28 12:44:12 +0000 UTC
`time.Parse()`	Parses a formatted string and returns the corresponding `time.Time` object.	`time.Parse("2006-01-02 15:04:05", "2024-08-28 12:34:56")` returns 2024-08-28 12:34:56 +0000 UTC
`time.Format()`	Formats a `time.Time` object into a string according to the specified layout.	`time.Now().Format("2006-01-02 15:04:05")` returns 2024-08-28 12:34:56
`time.Add()`	Adds a duration to a `time.Time` object, returning a new `time.Time`.	`time.Now().Add(24 * time.Hour)` returns the same time tomorrow.
`time.Sub()`	Subtracts one `time.Time` object from another, returning the duration between them.	`time.Now().Sub(pastTime)` returns the duration since `pastTime`.
`time.Since()`	Returns the duration since the specified `time.Time`.	`time.Since(startTime)` returns the duration since `startTime`.
`time.Sleep()`	Pauses the current goroutine for at least the specified duration.	`time.Sleep(2 * time.Second)` pauses for 2 seconds.
`time.UTC()`	Returns a `time.Time` object corresponding to the specified UTC time.	`time.UTC(2024, 8, 28, 12, 34, 56, 0)` returns 2024-08-28 12:34:56 +0000 UTC
