the strftime is depicted in newer php versions

line 126: 'date' => strftime('%F %T', $TIME),

not the most eloquent time format but at least this worked:

ADD:
date_default_timezone_set('America/New_York');
$date = new DateTimeImmutable();

REPLACED:
'date' => strftime('%F %T', $TIME),
WITH:
'date' => date("Y-m-d\TH:i:s\Z",$TIME),

** would like the Z to show milliseconds

Not sure what the following does, but times are correct on filtered list???

if ($filter_date->format('Y-m-d') != strftime('%F', $TIME))
{
continue;
}
