Countdown is a variable that tells you the amount of time till a certain date has passed
This variable requires one parameter, that is the timestamp that it needs to count down to. For example
$(countdown 2020-01-01 00:00:00) will make the bot calculate the time till 1st Jan 2020.
To use a specific timezone you can add the UTC offset to the timestamp. For example
$(countdown Aug 25 2019 00:00:00 GMT-0400) would use the EDT as the timezone.
