Como converter o tempo epoch em uma data legível por humanos?

import datetime
# Convert epoch to human readable date
epoch = 1631532000
human_readable_date = datetime.datetime.utcfromtimestamp(epoch).strftime('%Y-%m-%d %H:%M:%S')
print(human_readable_date)

// Convert epoch to human readable date
const epoch = 1631532000;
const humanReadableDate = new Date(epoch * 1000).toISOString().replace(/T|Z/g, ' ');
console.log(humanReadableDate);

import java.text.SimpleDateFormat;
import java.util.Date;
// Convert epoch to human readable date
long epoch = 1631532000;
Date date = new Date(epoch * 1000);
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
String humanReadableDate = sdf.format(date);
System.out.println(humanReadableDate);

using System;
// Convert epoch to human readable date
long epoch = 1631532000;
DateTime date = new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc).AddSeconds(epoch);
string humanReadableDate = date.ToString("yyyy-MM-dd HH:mm:ss");
Console.WriteLine(humanReadableDate);
