From your usage of date I would guess that you are (1) using Gnu utilities and therefore (2) are on a Linux distro and therefore (3) using bash.
Try this:
Adding -r to ls allows us to use head instead of tail. Also, it is unlikely that
there will be a directory with the .txt extension the the -p and the grep should not be needed. The -A is also useless in this context.
The variable expansion ${var:offset:len} will produce len characters from the offset position (starting from zero), so ${filename:0:8} will produce 20171003.
date will understand 20171003 as 3rd October 2017 so you don't need to chop up the date.

echo $date->format('Y-m-d H:i:s') . "
";

echo $date->format('Y-m-d H:i:s') . "
";
$date->setTime(14, 55, 65);
