Over the years, I've missed many meetings due to timezone miscommunications. To solve this, I've created TimeZone GPT, a foolproof tool that accurately converts and resolves times from any input.<p>I know that Google provides similar functionality, but I always mess it up somehow...<p>TimeZone GPT uses OpenAI's gpt-4o model to understand the inputs, and then TimeAPI to resolve the current timezone information and make the conversion.<p>I gamified it a bit, so that I record what are the other people inputs, their timezones (as resolved by their IP), and the model outputs. This will allow me to capture edge cases that I've not considered.<p>I don't expect many other folks to be using it, but I wanted something that would at least solve my problem.
