Or who was born first, either in the case of twins, or relatives of the same degree
born close together. I have distant sibling nieces whose first children were born
maybe a day or a few days apart, as the birth announcements were emailed some unknown
time after the events and gave no details, unlike traditional print announcements.

I have known companies who had hash generated employee id collisions, where employees
who happened to have exactly the same name and birth date were hired on the same date
in distant divisions, and there were obviously no existence or collision handling
checks, or tie breaking provisions, built into the systems.

Murphy knows there will be cases when unlikely events will occur on the same date or
at the same time. I have fixed systems where "will never happen" took from six days
to six months to occur after release: never seen a system with a "will never happen"
design decision where "never" was more than six months between release and fix dates!

Take care. Thanks, Brian Inglis
