I agree that when the birth-hour is unknown that it could be assigned to a time other than midnight to 00:59:59 or 02:00 to 03:00 to avoid most DST transition problems. We looked into the possibility of changing that default time ourselves, but it appears to be in protected code by the software manufacturer. We are working with the manufacturer to avoid the problem in a future version of the software. We have not heard if the manufacturer will alter the default birth hour to noon or another time.
Most systems I worked on had such values as parameters in a database table for system parameters and/or business rules indexed by a key value such as TIME_OF_DAY_BIRTH_TIME_DEFAULT. Suggest this as a more flexible solution to your vendor.
The article you linked on birth hours is very interesting. Most of our problem patients had birth dates between 1930 and 1941 and were likely born without modern interventions that are mostly scheduled during daytime hours.
As the article stated, non-induced vaginal births occurred with a flat distribution around the clock. -- Take care. Thanks, Brian Inglis, Calgary, Alberta, Canada This email may be disturbing to some readers as it contains too much technical detail. Reader discretion is advised.
