Arrow中时间戳的区别

Question

我如何让Arrow返回两个时间戳之间的小时差异？

这就是我所拥有的:

difference = arrow.now() - arrow.get(p.create_time())
print(difference.hour)

p.create_time() 是当前正在运行的进程的创建时间的时间戳.

返回:

AttributeError: 'datetime.timedelta' object has no attribute 'hour'

编辑:我不想要所有三种格式的总时间,我希望它作为余数,例如."3天,4小时,36分钟"不是"3天,72小时,4596分钟"

Answer 1

给定2个日期格式,从字符串到arrow类型.

>>> date_1 = arrow.get('2015-12-23 18:40:48','YYYY-MM-DD HH:mm:ss')
>>> date_2 = arrow.get('2017-11-15 13:18:20','YYYY-MM-DD HH:mm:ss')
>>> diff = date_2 - date_1

区别在于datetime.timedelta数据类型.

>>> print type(diff)
<type 'datetime.timedelta'>

并导致:

>>> print diff
692 days, 18:37:32

要使其格式化,以便您可以分别D days, H hours, M minutes, S seconds获得日期,然后使用divmod函数获取其他信息.

>>> days = diff.days # Get Day 
>>> hours,remainder = divmod(diff.seconds,3600) # Get Hour 
>>> minutes,seconds = divmod(remainder,60) # Get Minute & Second 

结果将是:

>>> print days, " Days, ", hours, " Hours, ", minutes, " Minutes, ", seconds, " Second"
692  Days,  18  Hours,  37  Minutes,  32  Second
