Idiom #98 Epoch seconds to date object

Convert a timestamp ts (number of seconds in epoch-time) to a date with time d. E.g. 0 -> 1970-01-01 00:00:00

#include <chrono>
#include <ctime>

std::time_t d = std::chrono::system_clock::to_time_t(ts);

var d = DateTimeOffset.FromUnixTimeSeconds(ts).UtcDateTime;

import std.datetime, std.stdio;

auto d = SysTime(unixTimeToStdTime(ts), UTC());

var d = new DateTime.fromMillisecondsSinceEpoch(ts, isUtc: true);

Timestamp = {Seconds div 1000000, Seconds rem 1000000, 0},
calendar:now_to_universal_time(Timestamp).

import "time"

d := time.Unix(ts, 0)

import Data.Fixed (Fixed(MkFixed))
import Data.Time.Clock (secondsToNominalDiffTime)
import Data.Time.Clock.POSIX (posixSecondsToUTCTime)

d = posixSecondsToUTCTime . secondsToNominalDiffTime . MkFixed $ toInteger ts

new Date (ts * 1000)

import java.text.SimpleDateFormat;
import java.util.Date;

Date d = new Date(ts * 1000);
SimpleDateFormat f = new SimpleDateFormat();
f.applyPattern("yyyy-MM-dd HH:mm:ss");
String s = f.format(d);

import static java.lang.System.currentTimeMillis;

long ts = currentTimeMillis();
String d = "%tc".formatted(ts);

import java.util.Date;

Date d = new Date(ts * 1000);

import java.time.Instant;

Instant d = Instant.ofEpochSecond(ts);

import java.time.LocalDateTime;
import java.time.ZoneOffset;

LocalDateTime d = LocalDateTime.ofEpochSecond(ts, 0, ZoneOffset.UTC);

$d = DateTime::createFromFormat('U', $ts);

uses SysUtils;

var
  D: TDateTime;
  TS: TTimeStamp;
begin
  D := TimeStampToDateTime(TS);
end.

use DateTime qw();

my $d = DateTime->from_epoch(epoch => $ts)->strftime('%F %T');

import datetime

d = datetime.date.fromtimestamp(ts)

require 'date'

d = DateTime.strptime(ts, '%s')

extern crate chrono;
use chrono::prelude::*;

let d = NaiveDateTime::from_timestamp(ts, 0);

Do you know the best way to do this in your language ? New implementation...
