We are especially interested in this as part of the Palomar-Quest 
survey, since it has repeated passes. I have made some kind of a 
bastard SIAP with time for myself, based on regular expressions for 
string-matching of dates.

Every dataset is labeled by date-string, eg 20060425 means today. And 
so the regular expression "200604*" means everything from April 2006, 
".*" means everything, or you can be specific with "20040423|20040522" 
means anything from either of those dates.

Another alternative is to give an exact time (eg MJD) to each image, 
and specify a time interval that way.
