Describe the bug
When I go to a chat, and my browsers locale is set to 12 hour AM PM time (something I still have not managed to get to change without also changing the browsers language unfortunately). The timestamps in chat are showing as AM PM datetime format, but on hover it shows as 24 hour time
To Reproduce
Steps to reproduce the behavior:
- Go to any chat with browsers locale set to EN_US
- Observe how time displayed above message is AM/PM format
- Hover over same message
- Observe the time in 24 hour format
Expected behavior
The same time format in both cases
