I vote for user control over this.  The default should probably be  
peak.  This is not always something that has been measured or is  
measurable (or predictable).  In addition to the publishing timestamp  
(what does "issue" mean?) and physically significant timestamps such  
as peak flux, there is also a possible discovery timestamp.  I can  
imagine a VOEvent subscriber or client application being interested  
in any of these for various purposes, but the default interface  
should reflect the key science use case(s) for the different event  
streams.

Would also like to be able to filter an event stream based on  
estimates of when a transient will no longer be visible using a  
particular telescope and instrument, for instance.  These estimates  
would typically require an exposure time calculator.

This time domain stuff is lots of fun!

NO BLINK, no blink, NO BLINK - it's aNnOyInG.  How about a different  
(user selectable) color?
