Through mechanisms such as the Network Time Protocol (NTP), a computer maintains accurate current time, calibrated to minute fractions of a second. Such precision makes it possible for networked computers and applications to communicate effectively. The timestamp mechanism is used for a wide variety of synchronization purposes, such as assigning a sequence order for a multi-event transaction so that if a failure occurs the transaction can be voided. Another way that a timestamp is used is to record time in relation to a particular starting point. In IP telephony, for example, the Real-time Transport Protocol (RTP) assigns sequential timestamps to voice packets so that they can be buffered by the receiver, reassembled, and delivered without error. When writing a program, the programmer is usually provided an application program interface for a timestamp that the operating system can provide during program execution.
