Features

• Messy Time Recognition
  Advanced regex detects time mentions like 10 00AM, 7pm, 5:30 am, 8: 00PM, etc.

• Timezone Auto-Conversion
  Replies to each user ephemerally with the time converted to their Slack-set timezone, including Daylight Saving Time adjustments.

• Private and Clutter-Free
  Uses ephemeral messages --- no message flooding, only the intended user sees the converted time.

---

Known Limitations

• Ambiguous Timezones Not Handled
  Timezones like ET or NZST are skipped due to conflicts (e.g., ET = Eastern Time or Egyptian Time).

• No Conversion for Bots
  Bots don't have timezones set via the Slack API, so no conversions are sent to them.

• No Replies in Threads
  The Slack API does not allow ephemeral message replies in threads, the bot however will to reply to all conversions in threads within the channel

Use Case

"Meeting at 9:30am tomorrow PST"
Every human user will get a private message showing the converted time in their own timezone, taking DST into account.

How It Works

1. Listens to messages in real-time using Slack's Socket Mode.

2. Parses timestamps using smart regex.

3. For each human user in the thread or channel:

   • Fetches their timezone via Slack API.

   • Converts time using zoneinfo with DST awareness.

   • Replies with a clean ephemeral message.
