'''
The purpose of this template is to create a Discord bot that sends a message once a day at a random time.
Obvioulsy, you can modify sync time, sleep time, etc. to suit your needs.

In order to run properly, you'll have to add the channel ID in which the message will be sent, the message you want to send and your bot Token ID.
Be careful with your Token ID, you have to keep it secret. Do not share it with anyone !
