Getting Started With Timein London
I picked this up after spending two weeks trying to coordinate meetings between clients in London and teams across three other continents. The kind of back-and-forth where you end up at 11pm wondering if you meant 11am or 11pm British time, then double-checking whether the UK had rolled the clocks forward that same weekend. Annoying isn't the word for it. Timein London is essentially a specialized time tracking and scheduling tool built around London as a base reference point. It gives you real-time visibility into London time across different contexts—work hours, market opens, transportation schedules, and so on. The idea is that instead of juggling multiple converters, you have one place that handles it all. Here is how I actually got it running on my setup:
First, you go to their website and sign up. The free tier covers basic time display and one timezone anchor, which is fine if you are just checking whether it is morning or evening in London. The paid plan unlocks multi-schedule views and API access. I went with the paid version after a month because the free tier was missing too much for actual work use. Once logged in, the dashboard loads with London time front and center. You can add other timezones by clicking the plus icon next to the main clock. It shows the offset and current local time side by side. Overlapping working hours between London and whatever timezone you add appear highlighted in green. That feature alone saved me about an hour a week of mental math I used to do by hand. The mobile app mirrors the desktop experience. Download it from either the App Store or Google Play. Log in with the same account and it picks up where you left off. I keep it on my home screen as a widget. The lockscreen widget shows London time and your secondary timezone in a single glance. Useful when I am traveling through airports and need to know what time it is at home before I even connect to Wi-Fi.
There is a calendar integration as well. Connect it to Google Calendar or Outlook and the tool will tag every event that falls within London business hours with a color code. Events that overlap with your London contacts get flagged automatically. I set it to highlight anything between 9am and 5pm London time in blue so I can spot conflicts at a glance when reviewing my week. One thing people miss: you can set up custom recurring events that only appear in the London view. If you have a weekly standup at 3pm London time but your team is scattered, the tool will show you exactly when that translates to in each person's location without you having to calculate it manually each week. Here is where things get slightly tricky. I ran into an issue where the daylight saving transition dates were not syncing properly on my Android device. The app showed London as being one hour off for about three days after the clocks changed in March. I checked the settings and found that the automatic timezone update for the app was disabled by default. Going into Settings under the Time & Date section and toggling "Auto-update timezone" to on fixed it immediately. Worth noting if you notice the same thing happening.

The API is fairly straightforward if you need to build something custom. You get an API key from the dashboard settings page. The endpoints return JSON with current time, timezone offset, and daylight saving status. Rate limits sit at 1000 requests per hour on the standard plan. More than enough for personal use but you will need to upgrade if you are running this through an automation script that checks every minute. Now, a few things this tool does not do well. It does not handle historical time lookups very gracefully. Asking for what time it was in London on a specific past date will give you the right answer, but the interface is clunky and slow. If you need to audit past meeting times or check records, you are better off using a dedicated historical timezone library instead. Another limitation: the tool assumes London is your primary reference. If your business is based in another city and you just occasionally coordinate with London, you will find yourself constantly switching the anchor point, which defeats most of the convenience. In that case, a general multi-timezone app like World Time Buddy or Timeanddate.com might serve you better.
The export feature is present but basic. You can pull your schedule as a CSV file, which works fine for backup purposes. However, the format strips out some of the color coding and grouping logic, so do not expect a perfect mirror of your dashboard when you open the file elsewhere. Support is available through their help center and email. Response time averages about two business days, which is reasonable. The live chat feature appears intermittently and was down the last time I tried to use it, so rely on email if you run into something urgent. If you primarily deal with London-based stakeholders and need a reliable way to track their time alongside your own, this tool does the job. It is not fancy. The design is utilitarian at best. But it works consistently once you get past the initial setup quirk with the auto-update toggle.
