EJB timers ignoring start date

I am using the EJB timer scheduler for some recurring tasks in my application. There are 3 of them, designed to run overnight, every night (i.e. every 24hours).

All works well when I deploy the application, and on subsequent deployments. However, when I restart JBoss, the timers run every 24 hours after the RESTART, rather than the proper scheduled time.

My timer table looks like:

Code:

select TIMERID, TARGETID, INITIALDATE, TIMERINTERVAL from TIMERS;
------------------------------------------------------------------------------------------------
----------------------------------------------------+

------------------------------------------------------------------------------------------------
----------------------------------------------------+

------------------------------------------------------------------------------------------------
----------------------------------------------------+

So, it I restart JBoss at 6pm, July 12th, the tasks will next run at 6pm July 13th, rather than the expected 1am, 1.05am and 2am 13th July.
