Abstract
A message processor accesses an electronic message. The message processor identifies from within the electronic message any schema-based time markers including time related message data associated with the message processor. The message processor determines if a schema-based time marker within the electronic message should be modified. This can include signing a portion of time related message data to indicate to a subsequent message processor that the time related message data can be trusted. The message processor routes the message (either directly or through one or more intermediary message processors) to a destination message processor. The destination message process receives the message and processes the electronic message according to time related message data included in the message. This can include trusting the portion time related data that was singed by the message processor.
