The Select Queue Time attribute dialog box is for specifying the Execution 
Time attribute relationship to consult (when to queue), when limiting the list
of jobs appearing on the Jobs listbox in the main xpbs window.

Enter a valid logical operator in the Queue Time spinbox, and click
"on either the date/time button, or on the wildcard button "ANY" to setup a
logical relationship to consult when restricting the list of jobs.

For the date/time button, the valid Queue Time operators are "=", "!=", ">", 
">=", "<", "<=". But for checkpoint value "ANY", the valid
operator is "=" only.

Specification of date/time parameter is done by manipulating the hour, minutes,
seconds, month, day, year spin boxes.
