> When using JDBC persistence artemis checks for time differences between the 
> broker and the database. Currently this check requests the time of the 
> database and compares it to the system time before and after sending this 
> query by removing the milliseconds and verifying that the database time is 
> between the start and the end time. 
> This leads to somehow random warnings in the log depending on the current 
> milliseconds when this check is performed. 
> For example if the time on your artemis server is 00:00:01.000 before the 
> check and the time on the database is 00:00:00.999 it will log a warning 
> although there is only 1 millisecond difference. On the other hand if your 
> artemis server time is 00:00:01.000 after sending the query and the database 
> time is 00:00:01.999 there will be no warning although the time is 999 
> milliseconds after the end time.
> Therefore it would be better to use a consistent margin for the database time 
> during this check. To avoid problems in setups where the system times are not 
> well synchronized, this time margin should be configurable to allow the user 
> to fine tune it.
