Default default for last event time

Hi,

What is the default value for the last_event attribute? For example
what will be s'last_event when previously no action performed on "s"?
In modelsim it seems it is a very big value.

If there's no such event, it's supposed to return TIME'HIGH which is
technically undefined (implementation dependent), although it's often
2^31-1 ns.
