broken rss feed

Hello Thom,
Since the last update of the plugin, the RSS feed has not worked since March 8, 2019.
I tested with the standard RFC 822 like this (in feedaway.php):
-> options [‘daymonth’] == ‘md’? m / j / Y H: i ‘:’ d / m / Y H: i: s +0000 ‘;
It worked before the update but not anymore.
