SamlSecurityToken.ValidFrom Property

Gets the first instant in time at which this security token is valid.

Namespace:  System.IdentityModel.Tokens
Assembly:  System.IdentityModel (in System.IdentityModel.dll)

public override DateTime ValidFrom { get; }

Property Value

Type: System.DateTime
A DateTime that represents the first instant in time at which this security token is valid.

Use the ValidFrom and ValidTo properties to determine the time period in which a SamlSecurityToken token is valid. The ValidFrom and ValidTo properties represent the first and last instants in time in which the security token is valid, respectively.

By default, a 5-minute clock skew is allowed between the sender and receiver of the security token. So, if the NotBefore property is set to 1:00 PM, then the ValidFrom property is set to 12:55 PM.

When the ValidFrom property is set to MinValue, then the SAML assertion associated with this SamlSecurityToken security token does not have any conditions set.
