Overview

## What Timezone Buddy does

Timezone Buddy answers scheduling questions for people spread across regions. Given an IANA time zone identifier it reports what the clock reads there now, converts a specified date and time into several zones at once with daylight saving shifts applied automatically, and works out the hours during which members of a distributed team are all available.

Those three operations are what the record covers. Calendar integration, saved team rosters, working hour preferences, and creating an event once a window is found are not mentioned. The developer is listed as xuhuan. Working from IANA identifiers rather than abbreviations avoids the ambiguity of labels that map to more than one offset.

### Who it is for

Distributed teams and anyone regularly booking calls across several countries.

### What stands out

Daylight saving transitions are resolved inside the conversion instead of being left to manual arithmetic.

## Where Timezone Buddy is listed

Timezone Buddy is listed in the ChatGPT apps directory only. xuhuan has no connector under the same domain in the Claude directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.

ChatGPT apps are built on MCP, and the same server can back a Claude connector, so the absence is a distribution decision rather than a technical one.
