Remote work changed how I think about time.
In an office, everyone operates on the same clock. 2pm is 2pm for everyone. After going remote, I'm coordinating with people on 4 different continents. "Let's meet at 2pm" stopped meaning anything obvious.
The Daily Friction Points
Scheduling calls: "What time works for you?" involves mental math: they're UTC+1, so my 10am is their... wait, is their DST currently active? My 10am Eastern might be their 3pm or 4pm depending on the month.
Knowing when to send messages: Pinging someone at 11pm their time for a "quick question" creates awkward dynamics. I'd rather know it's late there and schedule the message.
Casual context: "She's dealing with a storm" means more when you know what time it is there and can picture someone in their actual day.
What I Set Up
My browser's new tab page shows world clocks for each city where I have regular contacts. I use Weather & Clock Dashboard for Firefox, which puts clocks (and local weather) on every new tab.
The setup took 5 minutes:
- Install the extension
- Open settings in the new tab
- Add cities: I have San Francisco, London, Berlin, Singapore, São Paulo
Now every time I open a new tab, I see all five clocks. I don't have to think "what time is it there" — I just know, passively.
What This Changes
The main effect is that I stopped making assumptions. Before, I'd message someone at what felt like a reasonable hour and later realize it was unreasonable for them. The mental model just wasn't there.
Seeing the clock constantly builds a background understanding of where everyone is in their day. When it's 9pm in Singapore on my new tab, I mentally file "they're done for the day, don't expect fast replies."
A secondary effect: I'm better at scheduling. When proposing meeting times, I can quickly scan my new tab and see what times overlap reasonably. No calculator, no timezone converter website, just a glance.
The World Clock Design
The world clocks in Weather & Clock Dashboard show:
- City name (what you configured)
- Current time
- Day of week — this is subtle but important. When you're scheduling across a date line, knowing it's "Tuesday in Sydney vs Monday in New York" matters.
The extension also shows local weather for each city, which I didn't think I'd use but actually helps contextualize what people are dealing with.
For Who This Is and Isn't
This helps if:
- You regularly coordinate with 2+ time zones
- You want passive awareness (seeing clocks when you open tabs) rather than active lookup
- You use Firefox as your main browser
Less useful if:
- All your contacts are in the same timezone
- You prefer a dedicated world clock app with more features (alarms, converters, etc.)
- You need to know more precise offsets for DST calculation (the extension shows current time, not offset)
The goal of a world clock on a new tab isn't to solve timezone math — there are apps for that. It's to build a mental model of your team's day that you carry around without thinking about it. That's what actually reduces the friction in remote coordination.
