A method, system, and computer program product for transparent configuration of virtual hosts to support timestamping of documents that are processed in multiple time zones within an enterprise platform. Embodiments use network address translation and virtual host initialization techniques to configure a port listener such that the port listener receives IP packets from the network interface and uses the subnet's network address IP address to map to a time zone correspondence. When the identified time zone corresponds to a first time zone, then the port listener forwards the IP packet to a first virtual host process that has been initialized with a first time zone virtual time clock used for timestamping. When the identified time zone corresponds to a second time zone, the port listener forwards the IP packet to a second virtual host process that has been initialized with a second time zone virtual time clock used for timestamping.
