時(shí)間戳：

時(shí)間戳是指格林威治時(shí)間1970年01月01日00時(shí)00分00秒(北京時(shí)間1970年01月01日08時(shí)00分00秒)起至現(xiàn)在的總秒數(shù)。使用時(shí)間戳僅用四個(gè)四節(jié)保存日期時(shí)間，可用于日志、版本號(hào)中時(shí)間的保存和傳輸

---

引用的庫(kù)：

#include <time.h>
庫(kù)內(nèi)時(shí)間接頭體定義：struct tm
時(shí)間轉(zhuǎn)時(shí)間戳庫(kù)函數(shù):mktime
時(shí)間戳轉(zhuǎn)時(shí)間函數(shù)：localtime
