How do you handle time zone confusion when working globally?

Working with international teams has been amazing, but time zones? Not so much.

I’ve personally missed meetings because I miscalculated PST vs GMT 

Curious how everyone here handles time conversions across Slack, LinkedIn, emails, etc.

Do you:

• Manually Google it?

• Use a world clock?

• Just calculate in your head?

We recently built HoverTime, a lightweight browser tool that automatically converts any time you see online into your local time.

But I’d genuinely love to know how you're solving this today?
