Problems with mimimum value for DateTime Package Variable since SP1

Since I've installed SP1 the minimum value for a package variable has changed.

The former version used 12/30/1899 as the minimum value that can be entered.
Now the min value has changed to something about 1960.

During package execution I'd like to distinguish between two states:

1. The Variable has not yet been written to.
2. Any of my executable has written to it.

At the moment I check the value of it to be the minimum value (see above) or not.
So if I develop packages under SP1 I get into trouble.

Any way out of it?
Thanks

[EDIT] The mindate in C# differs from both date values mentioned above! Consistency? Hum![/EDIT]

How did you determine that you can't put values below 1960 in there? I (or more accurately Darren who is sat right next to me) has just typed the value 01/01/1900 into the variables window and it sems to take it OK.

What specifically are you not able to do?

Typing works fine, and the following code worked too.

Public Sub Main()

Dts.Variables("Variable").Value = DateTime.MaxValue
System.Windows.Forms.MessageBox.Show(Dts.Variables("Variable").Value.ToString())

Dts.Variables("Variable").Value = DateTime.MinValue
System.Windows.Forms.MessageBox.Show(Dts.Variables("Variable").Value.ToString())

Dts.TaskResult = Dts.Results.Success

End Sub

Sorry for posting too quick...
