Introduction
In this blog post, we will explore how to convert a Linux timestamp to UTC time format in the Go programming language. A Linux timestamp is a representation of time as the number of seconds since the Unix epoch (January 1, 1970, 00:00:00 UTC). Converting this timestamp to UTC time format is a common task when dealing with timestamps in Go.
Syntax
To convert a Linux timestamp to UTC time format in Go, we can use the time.Unix function. This function takes two arguments: the number of seconds since the Unix epoch and the number of nanoseconds since the Unix epoch. By passing the Linux timestamp as the first argument and 0 as the second argument, we can get a time.Time object representing the UTC time.

func main() {
timestamp := int64(1619082967) // Linux timestamp
utcTime := time.Unix(timestamp, 0)
fmt.Println(utcTime)
}
Output:

utcTime := time.Unix(currentTimestamp, 0)
fmt.Println(utcTime)
}
Output:

Conclusion
Converting a Linux timestamp to UTC time format in Go is a simple task using the time.Unix function. By providing the Linux timestamp as the first argument and 0 as the second argument, we can obtain a time.Time object representing the UTC time. This functionality is essential when working with timestamps in Go applications.
