(I have tried to capture relevant keywords in the subject field of this "Problem and bug" post).

Today I found out something funny in EPiServer 4.62. I create EPi-pages automatically based on input from another system.

The datetime properties on the pages was created like this:

DateTime? date = new DateTime(2099,1,1);//the date is actually passed in from another system EPiServer.Core.Property prop = new EPiServer.Core.PropertyDate(date.Value);

dates above 06.06.2076 created an OutOfRangePropertyValueExcpetion exception when the date wasa passed into the constructor of PropertyDate.
But changing the code to

DateTime? date = new DateTime(2099,1,1);//the date is actually passed in from another system EPiServer.Core.Property prop = new EPiServer.Core.PropertyDate(); prop.Value = date.Value;

Everything worked fine!

EPiServer.Core.PropertyDate.MaxValue==new DateTime(2076,6,6). But why is there an upper limit if it is ok to give the PropertyDate an value greater then this, but only if it is assigned through the Value property and not through the constructor.

So my question is: What is the idea behind the MaxValue on PropertyDate in EPiServer?
