@starkah Thanks for the PR 😄 . Requested some changes. Rest LGTM

@sidntrivedi012 @DelusionalOptimist What do you think?

I changed the timezone of my system to UTC to test the changes. The reminder works fine. Great job 👍 .

Just one thing, when sending a reminder the bot still uses its local timezone. So you'll need to modify reminder and nextmeetup functions too.

@daemon1024 @DelusionalOptimist thanks for pointing out the necessary changes. I'm on it.

@DelusionalOptimist Wouldn't it be more easier for the user if the reminder was in it's local time zone?
I suggest that in the first line of the reminder we could change it from "MEETUP REMINDER!" to " REMINDER - MEETUP IN 2 HOURS" or something similar. What do you think?

@starkah Note that the users are the members of OSDC and IST would be the local timezone for em :) But the bot can be deployed anywhere and the timezone of the developer's local system or any environment shouldn't be a dependency.

@daemon1024 Makes sense. I'll try to do that.

Some small nits rest LGTM.
