Answer 1

刚刚找到parsedatetime，用于解析Jon Clements提供的link中的人类可读日期/时间文本。如果您感兴趣，这是一个解决方案：

from time import mktime
from datetime import datetime
import parsedatetime as pdt

time_str = '1 hour ago'
cal = pdt.Calendar()
dt = datetime.fromtimestamp(mktime(cal.parse(time_str)[0]))
time_formatted = dt.strftime('%b %d, %Y %H:%M')
print(time_formatted) # will print something like: Dec 15, 2013 02:10
