"I had unintentionally changed the dote of birth of every one in my practice to 05-06-1908."
The above described error occurred while I was trying to set the date of birth on a gentleman in OpenEMR to 05-06-1908 and the software would not permit me to change to this date.
Is their a limit to the PHP date range? It seems that OpenEMR doesn’t permit dates prior to 1912 or so.
That’s pretty old. You might want to test it yourself on recent code to confirm that it’s an old problem that’s fixed now, and also consider biting the upgrade bullet.
