Hello Scott,
Sorry for the delay in response, but I was out of office the last week.
Yes, there are no registered plugins/workflows that is changing the dates. Like I already mentioned above, If i am trying to display the date in a page of the child dialog, it displays the expected value. However, when I use the same date ( obtained form parent dialog ) to create an appointment in the child dialog, it is doing the timezone conversion.
Thanks!
