Add Timezones to Datetime Attributes for Clarity

Internationalization Analyzer

What is this warning?

Your page includes a date and time but doesn't specify the timezone. This can be very confusing for a global audience. Is '9:00 AM' in the morning in New York, London, or Tokyo? Specifying a timezone removes this ambiguity and makes the information clear for everyone.

How to Fix This Issue

How to Fix It

The Problem

<time datetime="2023-12-25T09:00">Christmas Morning</time>

The Solution

Include the timezone offset or 'Z' for UTC in the `datetime` attribute.

<!-- Using UTC -->
<time datetime="2023-12-25T09:00Z">Christmas Morning</time>

<!-- Using a timezone offset (e.g., for New York) -->
<time datetime="2023-12-25T09:00-05:00">Christmas Morning</time>

Why This Works

Adding a timezone provides clear, unambiguous information to both users and machines (like search engine crawlers), which is especially important for time-sensitive content like event schedules.
