ABSTRACT
In digital environments, a time stamp is an electronic record enclosing the time of occurrence of an event. Time stamping refers to the use of an electronic time stamp to provide an order among a set of events. As part of the controls to e-records integrity, the system clock or networked master clock provides the date and time stamps required to e-records and e-signatures. Typically the networked master clock is placed in the time server. Date and time stamps create a notation that indicates, at least, the correct date and time of an action. It is recognized as a valuable service that supports nonrepudiation of transactions. Supporting time controls include an infrastructure that supports time stamping from a trusted time such as the coordinated universal. Controls should be established to ensure that the system's date and time are reliable in all computers connected to the local network.
