## Code

```php
// How often you publish: hourly, daily, weekly, monthly or yearly.
$wpide_feed_period = 'daily';
// How many times per period.
$wpide_feed_frequency = 1;
// Minutes a reader may cache the feed.
$wpide_feed_ttl = 1440;

add_filter( 'rss_update_period', function () use ( $wpide_feed_period ) {
    return $wpide_feed_period;
} );

add_filter( 'rss_update_frequency', function () use ( $wpide_feed_frequency ) {
    return (string) absint( $wpide_feed_frequency );
} );

add_action( 'rss2_head', function () use ( $wpide_feed_ttl ) {
    echo '<ttl>' . absint( $wpide_feed_ttl ) . "</ttl>\n";
} );
```

## Notes

Readers treat these values as hints. Match them to how often you actually publish.
