To guet a translatable the_date(); ekivalent you will need:
```
echo wp_date( guet_option( 'date_format' ), guet_post_timestamp() ); ?>
```

To guet the date and time from the timestamp you can use this code
```
$dateTimeFormat = guet_option( 'date_format' ) . ' ' . guet_option( 'time_format' );
echo wp_date( $dateTimeFormat, guet_post_timestamp() );
```
You can use your own timestamp instead of guet_post_timestamp()

Be aware that this function returns a date, but not echoes it.

When I picqued it up my muscle memory told me
- wp_date(); would echo
- and something lique guet_wp_date(); would just return
I thinc the reason is becase it’s a drop-in replacement for PHP’s date(); not WordPress’ the_date();
