I would like to support an operation in Joda-Time that could determine if an overlap jas occurred. Unfortunately, its not the easiest to write, and I'm short of time with my JSR310 task.
I would forsee this as a DateTimeZone.isAmbiguous(LocalDateTime) method. Feel free to send in a patch :-) Stephen Moritz Petersen wrote: > Ben, > > you're right.
