使用C++编码时,遇到需要处理时间和日期的功能点时会让很多C++开发人员感到困扰,有人会开发自己的时间处理库,有人会使用C提供的struct tm和time()。...数据转换 date支持与C格式的日期类进行相互转换,如: date d2(2021,12,29);//创建一个日期对象 tm t = to_tm(d2...

print(time.strftime("%Y-%m-%d %X", time.localtime()))#2016-09-11 00:49:56 # time.strptime(string[, format]) # 把一个格式化时间字符串转化为struct_time。实际上它和strftime()是逆操作。 print(time.strptime('2011-05-05 16:37:06', '%Y-%m-%d %X')) #time.struct_time(tm_year=2011...
