Describe the bug
After creating an issue with the date parameter set to a UTC timestamp, the main page displays a relative time that is several hours off from the actual date the issue was marked with (e.g. 1h ago for an issue that was made a few minutes ago).

Reproduction steps

1. Be in a non-GMT+0 timezone
2. Make an issue with a date in UTC, e.g. date: '2025-05-10T09:27:49.934Z'
3. Render cstate with this issue
4. Notice that the issue's relative timestamp is off by GMT+n hours, where n is your timezone's offset

Expected behavior
The relative time should be calculated with the knowledge that the timezone is UTC

Desktop (please complete the following information):

• OS: macOS
• Browser: Helium
• Version: Version 0.0.2.1 (Chromium 136.0.7103.92)

Additional context
It looks to be caused by 0b2ba23, which removed the UTC suffix from the data-date attribute in small.html.
