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 packet s so that they can be buffer ed by the receiver, reassembled, and delivered without error.
Most cases of shingles last 3 to 5 weeks. 1  The first sign is often burning or tingling pain; sometimes, it includes numbness or itching on one side of the body.  Somewhere between 1 and 5 days after the tingling or burning feeling on the skin, a red rash will appear.
This rash is similar to chicken pox and can take seven to 14 days to scab over. Typically, another one to two weeks are needed for the lesions to completely heal. A simple course of shingles can last anywhere from one month to several months. The severity and duration of the infection are dependent on the age and health of the affected person.
