1、time模块 time时间模块 在Python中,通常有这几种方式来表示时间: 时间戳(timestamp):通常来说,时间戳表示的是从1970年1月1日00:00:00开始按秒计算的偏移量。我们运行“type(time.time())”,返回的是float类型。 格式化的时间字符串(Format String) 结构化的时间(struct_time):struct_time元组共有9个元素...
INTERVAL DAY (day_precision) TO SECOND(fractional_seconds_precision) 存储一个时间间隔,day_precision说明天的整数位数,最多9位,默认2位。fractional_seconds_precision说明秒后面小数位数,默认6位,最多9位。 一 般将前四种数据类型DATE, TIMESTAMP, TIMESTAMP WITH TIME ZONE和TIMESTAMP WITH LOCAL TIME ZONE ...
DATEADD和TIMESTAMPADD处理季度(3 个月间隔);DATEDIFF和TIMESTAMPDIFF不处理宿舍。 %TimeStamp 格式化 如果timestamp-exp参数采用%Library.TimeStamp数据类型格式 (yyyy-mm-dd hh:mm:ss.ffff),则适用以下规则: 如果timestamp-exp仅指定时间值,则在计算生成的时间戳之前,timestamp-exp的日期部分设置为“1900-01-01...
month to October 31 yields December 1, the normalized form for November 31. 简单翻译一下: AddDate根据指定的年、月、日数字,加到原来的time类型值上并返回。比如对于 2011-1-1 这个日期,执行AddDate(-1, 2, 3)会返回 2010-3-4 AddDate将它的结果按实际日期进行标准化,所以,比如在10月31日加上一个...
