This method is normally called with the lifetime that arrived in the RST. In the default implementation, the token lifetime is calculated according to the following table.

Created (in)	Expires (in)	Created (in)	Expires (out)
null	null	DateTime.UtcNow	DateTime.UtcNow + SecurityTokenServiceConfiguration.DefaultTokenLifetime
C	null	C	C + SecurityTokenServiceConfiguration.DefaultTokenLifetime
null	E	DateTime.UtcNow	E
C	E	C	E

This method is called from the default token issuance pipeline implemented in the Issue method. For more information about the token issuance pipeline, see the Claims Issuance Pipeline topic.
