Time Zone Desk
Time Zone Desk, a small reckoner that computes in your browser and stores nothing. No account, no cloud, no telemetry.
This is not a screenshot. It's the real tool, running right here: go on, put something in it.
Forged into a knife, this tool ages with use: the blades you reach for wear soft, entries you tend keep their bloom, and the years travel with the file through every reforge.
Your client is in Denver, your mother is in Auckland, and the call is at nine — somebody's nine. The Time Zone Desk lines up the world's clocks so you can see what a given hour means in each place before you promise it to anyone. It computes, you compare, and no meeting gets scheduled for 3 a.m. by accident again.
Standing facts
- One HTML file. Opens in any modern browser, on any operating system.
- No account. No login, no sign-up, no e-mail wall.
- No cloud. Nothing leaves your browser: no server, no telemetry, no analytics.
- Yours forever. The file keeps working whether or not Offline.Ltd does.
- Ages with use. Entries you tend keep their bloom; the years travel with the file through every reforge.
In ten years
Time Zone Desk computes; it doesn't hoard. Open the file in 2036 and it will do the same arithmetic it does today, because the arithmetic is written into the file and nothing about it needs a server to agree.
If Offline.Ltd closes tomorrow, nothing on your machine notices. That isn't a marketing promise; it's simply what a file is.
Getting your data out
There is nothing locked in to get out: copy the numbers, or keep the file. Either way you owe no one a request form. No export queue, no "we'll e-mail you a link within 48 hours", no format that only one vendor can read.
Copy the file to a USB stick, a NAS, a folder your devices already sync. It runs on Windows, macOS, Linux, Android and iOS, online or off, because a browser is the only thing it ever needed.
Who else sees this
Nobody. Time Zone Desk works out its answer in your browser and forgets it the moment you close the tab: there is no store to breach, because nothing is stored. There is no account, no telemetry, no analytics, and no code in the file that opens a network connection, pull the cable and watch it carry on working. How privacy works across the Reckoners tools →
Questions people ask
How do I figure out what time a meeting is in another time zone?
Set your hour and see it translated across the zones you care about, side by side. The comparing takes seconds; the apologising you will no longer need took longer.
Does the Time Zone Desk track me or need my location?
No. It is one HTML file running offline in your browser — it computes times and stores nothing, asks for no location permission, and nothing leaves the page.
Who is this for?
Freelancers with far-flung clients, families scattered across continents, and anyone who has ever typed is it tomorrow in Sydney into a search bar at midnight.
