-------------------------------
What exactly are you trying to do?
datetime.max will give you
{code:java}
9999-12-31 23:59:59.999999{code}
How exactly do you want to add interval time to a start date which is the
maximum possible value?
> 'OverflowError: date value out of range' when setting 'start_date' to
> datetime.max
