Zonely

Timezone conversions, right inside Slack.

Zonely watches for time mentions like 10am CST, 3pm India, or 10:00 AM – 12:00 PM (GMT) and replies in a thread with the equivalent time — converted into each teammate's own Slack-configured timezone.

No slash commands, no setup per message. Just add it to a channel and it takes care of the rest.
