Time
Use the 24 hour clock together with Coordinated Universal Time (UTC) if you are unable to tell which timezone your user is in.
Use a colon (:) between the numbers.
Use ‘to’ instead of a hyphen in date or time ranges. This makes it easier for screen readers.
Examples:
- We received your submission at 13:24 (UTC).
- Our system will be down for maintenance between 23:59 and 03:00 (UTC)
As the majority of our users will not be in this timezone, add the ability to convert to a local timezone if possible.
Suggestion to improve accessibility:
Please apply before 16:00 (UTC). What’s this in my timezone?
