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.
The pimples change to pus-filled blisters that break open and scab over in about 7 to 10 days. When the blisters are scabbed over, they begin to heal. The scabs usually heal and fall off about 2 to 4 weeks after the rash appears. Some people with shingles also may have a fever, headache, fatigue, or general achiness. In rare cases, a person can have the pain of shingles without getting a rash. Some people (usually older people) have more severe symptoms.
