Post public message with timezones of all participants

[evmcl]

We're finding some people not particularly mindful that others live in different time zones to themselves. Instead of just posting a message that is "Only visible to you," a public message with a summary of all participants time zones would be great!

E.g.:

mathieu: Can we chat tomorrow around 2pm?

Timezone Butler: 2pm CST = 3pm EST = 7am AEST

mathieu: Yeah, that's a bit early. How about 4pm?

Timezone Butler: 4pm CST = 5pm EST = 9am AEST

george: Sounds good. I should be sufficiently caffeinated by then. :-)

This is the exact feature I'm also looking for and for the same reason - so everyone will be aware of the times they post. This does exactly what I want, but doesn't seem to be compatible with Slack anymore https://channeltime.info/
