Typically, the nonce can be implemented as a counter (a sequence number) or as a timestamp.
现时标志通常能实现为计数器(一个序列数)或者时间戳。

Therefore, the counter value in the sequence table used for identifier generation is incremented regardless, preventing the same identifier from being generated several times.
因此，不管序列表中用于标识符生成的计数器值是否递增，都能防止多次产生相同的标识符。

That program counter points to some location in memory typically to the first instruction in the sequence.
