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.
For most healthy people, the lesions heal and shingles pain subsides within three to five weeks. It is possible, however, for this pain to continue well after the rash has healed. Sometimes, particularly in older people, shingles pain persists long after the rash has healed. This is known as postherpetic neuralgia.
