What is the best way to store timestamps considering time zones for universal processing?

The best way to store timestamps considering time zones is to use Coordinated Universal Time (UTC). This helps avoid issues with daylight saving time changes and time zone differences.

In Go, this is usually done using the time.Time type and the UTC() and Parse methods with a specified time zone.

Example:

package main

import (
    "fmt"
    "time"
)

func main() {
    now := time.Now().UTC() // current time in UTC
    fmt.Println("UTC time:", now)

    // Parsing time in UTC
    t, err := time.Parse(time.RFC3339, "2024-06-01T15:04:05Z")
    if err != nil {
        panic(err)
    }
    fmt.Println("Parsed time:", t)
}

Storing time in UTC simplifies processing and comparison of timestamps across different time zones.
