InstallDate resetting

[xrbbb3n]

Hello,

We have a problem with the InstallDate field resetting itself to the current date whenever a config item is updated. Is there a way to prevent this field from being automatically updated? Here is the definition we have for InstallDate:

{
Key => 'InstallDate',
Name => 'Install Date',
Searchable => 1,
Input => {
Type => 'Date',
Required => 1,
},
CountMin => 0,
CountDefault => 0,
},

Is there any documentation on what those fields do? Perhaps one of them is set wrong...
