Currently, only moderators can see lock timers, and that's only for questions.
Temporary locks on answers not showing lock duration
When a post is locked, it frequently causes consternation and frustration to users, as they feel their avenue to discuss things freely has been blocked. Mainly on meta. Often locks are just to slow things down when comments get out of hand (abusive) or a post is being continually vandalized, to give people time to go for a walk or sleep on it and come back with a better perspective.
It's then up to mods to explain it's temporary. In the case of answers it's up to the mod who locked the post to explain that to other mods! As they cannot see if the lock is permanent or not.
Can we please make the timer on all locked posts visible to all users? Including the permanent locks. It would make all our lives easier.
