public interface ClockProvider
Clock
used as the reference for now
when
validating the @Future
and @Past
constraints.
The default implementation will return the current system time. Plugging in custom implementations may be useful for instance in batch applications which need to run with a specific logical date, e.g. with yesterday's date when re-running a failed batch job execution.
Implementations must be safe for access from several threads at the same time.
