The irritation
After seeing sales calls land at dinner time, I wanted the contact's current local time to be visible in HubSpot before anyone reached for the phone.

Built because…
The real build story.
What I built
I built a paid HubSpot UI extension that reads a configured IANA timezone property and displays a live clock on contacts, companies, deals, tickets, orders, carts, custom objects, and help-desk records, with localized output across seventeen languages.
The hard part
Time zones combine daylight-saving transitions, changing regional rules, object-specific property configuration, localization, and records where the timezone value is missing or invalid.
Under the casing
Proof, not decoration.

Outcome and lesson.
Where it landed
What Time Is It? V2 is an active HubSpot app with settings, billing, migration support, email, and a sidebar card focused on one job. It is not a dialer, calendar, scheduling tool, or location-enrichment service.
What stayed
A live clock is more trustworthy when its source property is explicit. The app should show the record's configured time, not guess silently from incomplete geography.
Field notes
This project has a physical address.
In the playable workshop, What Time Is It? V2 lives in the Systems & Maps Lab as a timezone station. You can inspect it without unlocking anything.
