Python中的舍入时间 [英] Rounding time in Python

问题描述

在Python中对舍入分辨率进行控制的，与时间相关的类型执行h/m/s舍入运算的一种优雅，有效且Pythonic的方式是什么?

What would be an elegant, efficient and Pythonic way to perform a h/m/s rounding operation on time related types in Python with control over the rounding resolution?

我的猜测是，这将需要时间模运算.说明性示例:

My guess is that it would require a time modulo operation. Illustrative examples:

• 20:11:13％(10秒)=>(3秒)
• 20:11:13％(10分钟)=>(1分钟13秒)

我能想到的与时间相关的类型:

Relevant time related types I can think of:

• datetime.datetime \ datetime.time
• struct_time

• datetime.datetime \ datetime.time
• struct_time

推荐答案

有关datetime.datetime的取整，请参见以下函数: https://stackoverflow.com/a/10854034/1431079

For a datetime.datetime rounding, see this function: https://stackoverflow.com/a/10854034/1431079

使用示例:

print roundTime(datetime.datetime(2012,12,31,23,44,59,1234),roundTo=60*60)
2013-01-01 00:00:00
