Welcome!

I'd argue a smarter though less greedy approach is to provide a 30-60 second buffer on the bottom of the hour so if there are issues starting the bot in the first 30-60 seconds, or if there is a multi second "desync" as you claim, the user isn't charged unfairly.

The bot charges before the next hour: Please fix. It's very irritating when we stop the bot before the next hour begins but we're charged anyways.
