Callbacks

When a job runs, it will make a call to a Lua function in the form onJob# (where # is the job number).

e.g.

function onJob21(jn, utc, utcj)
  -- jn is the job number = 21
  -- utc is the real time (could be behind realtime if catching up)
  -- utcj is the utc time of this call including variance
end

job.set(21, '00:30:00') -- run every 30 minutes
