Chime.

Chime is time scheduler verticle which works on Vert.x event bus and provides:

• scheduling with cron-style, interval, union or custom timers:
  • at a certain time of day (to the second)
  • on certain days of the week, month or year
  • with a given time interval
  • with nearly any combination of all of above
  • repeating a given number of times
  • repeating until a given time / date
  • repeating infinitely
• proxying event bus with conventional interfaces
• applying time zones available on JVM
• flexible timers management system:
  • grouping timers
  • defining a timer start or end time
  • pausing / resuming
  • fire counting
• listening and sending messages via event bus with JSON
• publishing or sending timer fire event to the address of your choice

Chime is written in Ceylon and is available at Ceylon Herd

Runs with Ceylon 1.3.2 and Vert.x 3.4.1
