An optional internal clock in chat

If possible, we would like an optional Internal 24 hour clock in a discord group. This is so that international players from different time frames/regions can refer to the same guild time.

For example, we all want to know when who in the group will be free to play at a certain time, but the different time and regions make that difficult. So if we have an internal chat clock, we can all refer to the discord group chat time.
