Another broken permission...
essentials.time must give access to command /time (for checking the time).
But it work only if players have essentials.time + essentials.time.set.

What is the exact command being used and what essentials version are you on?

EssX build 251.
command /time show time only if you have essentials.time + essentials.time.set perms.

Please update to build 265 for a fix.
