Hi Mike
I think you just need the "function" date
on its own. That gives you the time now as the number of seconds since 1970, the reference you want is http://doc.tiki.org/Calculations#date not really the PHP date
function.
So probably something like: (untested)
(date (str H:i) (sub futureDate date))
The str H:i
part gives you the format, and those you can look up on https://www.php.net/manual/en/datetime.format.php
