jcal => use jcal

cmq agent that will emit to a given queue with a delay.
it will of course use a database for its own use

it will need to fetch time from a centralised time server

procedure too expose:
	cron { "time": "* * * * *", "emit": [...]}
	delay {}
	interval {}

cron are async, they are not garantie to run at exact time, but they are garantie to run once time set is done, timestamp will be needed for interval
