Yes!!!! This would be super helpful!
Great idea! I like Slack's way of showing the users local time. The forum does collect a timezone presumably automatically using browser settings at sign-up. It is editable in preferences.
Would you prefer to see timezone or local time on a users profile?
The local time is convenient. That definitely makes it easier.
Local time is now displayed in reply user dropdown (shown on desktop only) and on profiles about section but only for users that have specified a location to offer more privacy to those who have chose not to. Hovering will show the offset to your current timezone.
