On command /time, /thetime, /clock, players would recieve this info.
Your current local time is [Player time] [DST/]. Current server time is [Server time] [DST/] (Difference [+/- difference in hours (and minutes if that applies)]) "[Event name here (if event is active)]" will be held again in [Time until next event] |
Example:
Your current local time is 13:43 DST. Current server time is 6:43 DST (Difference -7 hours) "Farewell to Gaile" will be held again in 1 hour 17 minutes. |
Or possibly just the time on its own and /event would give you name of event, time until next one, time gaps (if different than 3 hours) and how many times will be held (not including current one (if one is active) and previous), possibly also locations where event is taking place.
If not that, at least add some of this in the performance dot, next to sever ip.
