@remind-me in -2 minutes

It does not dectect the input when it is in a comment of a comment :P read well the description and code :) it just detects for now when it is a single lined string and when it is a main comment to the post !! This is why your last reminder did not work @emrebeyler

@remind-me tomorrow

it works :)

Hey @adasq, I will notify you on July 10th 2018, 12:00:00 pm (UTC)
Later!

LOL okay...i was wrong !! reading the post again: Calling remind-me in posts won't create a reminder. :)

Hi @adasq!
You asked me in this comment to create a reminder.
It seems the time has passed!

-2 minutes seem not to be a valid date, that is why it is ignored.
