+-- processing of time types.

+ -- Delay until an interval of length (at least) D seconds has passed, or
+ -- the task is aborted to at least the current ATC nesting level. This is
+ -- an abort completion point. The body of this procedure must perform all
+ -- the processing required for an abort point.
+
+ procedure Delay_Until (T : Time);
+ -- Delay until Clock has reached (at least) time T, or the task is aborted
+ -- to at least the current ATC nesting level. The body of this procedure
+ -- must perform all the processing required for an abort point.
