There is a few classes to work with date, time and timezones:

Zend -> JPHP

  • DateTime -> Time, TimeZone
  • time -> Time::seconds() unix time in seconds (UTC), Time::now, Time::today
  • ??? -> Time::millis() unix time in milliseconds
  • microtime(1) -> Time::millis() / 1000
  • strtotime -> TimeFormat::parse
  • date -> TimeFormat::format

How to format a date?

use php\time\Time;

$time = Time::now();
echo $time->toString('d-m-Y');

// or you can use TimeFormat 

$tf = new TimeFormat('d-m-Y');
echo $tf->format(Time::now());

How to get a date with timezone?

use php\time\Time;
use php\time\TimeZone;

$moscowTZ = TimeZone::of('Europe/Moscow');

$time = Time::now(TimeZone::UTC());
$time = Time::now($moscowTZ);

 // 01 Jan 2013, Moscow timezone
$time = Time::of(['year' => 2013, 'month' => 1, 'day' => 1], $moscowTZ);

How to get the all timezones?

What use instead of DateTimeZone::listIdentifiers and timezone_identifiers_list?

use php\time\TimeZone;

var_dump(TimeZone::getAvailableIDs());

How to get a unix time of a Time object?

Use the Time::getTime() method.

use php\time\Time;

$stamp = Time::now()->getTime();

How to change year or month of a Time object?

$now = Time::of(['year' => 2010, 'month' => 1, 'day' => 15]); // 2010-01-15

$time = $now->replace(['month' => 5, 'year' => 2020]); // 2020-05-15

// or add ...

$time = $now->add(['year' => 5]); // 2015-01-15

You also can use day, sec, min, hour, millis.
