Get unix timestamp with `time()`
```php
php > echo time();
1678298613
```
Get formatted date via `date()` (see [docs](https://www.php.net/manual/en/function.date.php)) and note warning about timezones.
Get formatted [UTC]() time via `gmdate()` (see [docs](https://www.php.net/manual/en/function.gmdate.php))
```php
php > echo date("Y-m-d w/W");
2023-03-08 3/10
php > echo gmdate("Y-m-d H-i-s"); # W for week of year, w for day of week
2023-03-08 18-03-05
```

Get nicely formatted date/time. This is the more modern approach.
```php
php > $date_utc = new \DateTime("now", new \DateTimeZone("UTC"));
php > echo $date_utc->format(\DateTime::RFC850);
Wednesday, 08-Mar-23 18:04:00 UTC
```
