Clock utilities plugin is in beta, it may contain some bugs but they will eventually be fixed.
 
 
 
 Clock utilities adds command /timer that creates timer with specified time to pass. When time passes, alarm rings to inform player that the time is over.
 
 Command usage:
 
 /timer <time in s> [time in m] [time in h]
 
 
 
 permission:
 
 clockUtilities.timer - allows to use /timer command (default)
 
 
 
 This plugin is WIP, more content will be added soon. Please send your suggestions in the comments
