World ClockTime Zone Clock for Power BI

You get access to copy the Vega JSON spec directly from this page. Choose your cities, layout and styling with the controls, then paste the spec into Ataytis Vega Studio inside Power BI Desktop. Everything travels inside the spec, so there is nothing else to set up.

Ataytis Vega Studio is our free, Microsoft-certified Power BI visual for rendering Vega specifications inside your reports. Install it once from Microsoft Marketplace in Power BI Desktop, then paste in any spec.

Properly, which is the main reason this exists. A visual cannot look up a time zone database at render time, so the usual approach is a fixed UTC offset that is wrong for half the year. Instead, every daylight saving transition for the zones you pick is calculated when you copy the spec and carried inside it, with more than a decade of changes ahead. The clocks adjust on the right night, in both hemispheres, without you touching the report.

No. The time is read from the machine of whoever is looking at the report, so there is no table, no measure, no column and no refresh. It is correct the instant the report opens and carries on ticking while it is being read.

The spec would need copying again to pick up the new rules. Rule changes are rare and usually announced well in advance, and the visual holds its last known offset rather than breaking, so the worst case is an hour out until you re-paste. If you want to be certain, re-copying once a year takes a minute.

Up to twelve. The page warns you when the type is bigger than the room each zone has been given, and can size the visual to fit the zones automatically.

The picker carries the full IANA time zone list — over four hundred zones — grouped by region and labelled with its current offset, so there is no shortlist to fall outside of. The name shown beside each clock is separately yours to write, so a location can be labelled however your organisation refers to it rather than by whichever city the zone is named after.

Everyone sees the correct local time for each city you have chosen, wherever they are reading from. The clock is driven by the viewer’s device, so it is only ever as accurate as their system clock — which on a managed corporate machine is generally very accurate indeed.
