如何获取此日期字符串:
" 2015年1月1日"
并且,假设它在特定时区(例如" US-Mountain"),将其转换为POSIX时间戳?
像这样:
magic_parse_function("2015-01-01", pytz.timezone("US-Mountain")) -> 1420095600
我花了很长时间搜索文档和这个网站,玩意识/不知道日期时间对象,并且希望获得一个不太疯狂的解决方案。以下不起作用,最后两行输出相同,它们应相隔3600秒:
import datetime
import time
import pytz
timestring = "2015-01-01"
pacific = pytz.timezone("US/Pacific")
mountain = pytz.timezone("US/Mountain")
(year, month, day) = timestring.split('-')
year = int(year)
month = int(month)
day = int(day)
unaware = datetime.datetime(year, month, day, 0, 0, 0, 0)
# aware_pacific = pacific.localize(unaware)
# aware_mountain = mountain.localize(unaware)
aware_mountain = unaware.replace(tzinfo=mountain)
aware_pacific = unaware.replace(tzinfo=pacific)
print time.mktime(aware_pacific.timetuple())
print time.mktime(aware_mountain.timetuple())
答案 0 :(得分:3)
有三个步骤:
将日期字符串转换为天真的datetime
对象:
from datetime import datetime
dt = datetime(*map(int ,'2015-01-01'.split('-')))
获取时区感知日期时间对象:
import pytz # $ pip install pytz
aware = pytz.timezone("US/Mountain").localize(dt, is_dst=None)
is_dst=None
针对模糊或不存在的时间引发异常。这里' re more details about what is is_dst
flag and why do you need it, see "Can I just always set is_dst=True?" section
获取POSIX时间戳:
timestamp = aware.timestamp()
从Python 3.3+开始, .timestamp()
可用。请参阅multiple solutions for older Python versions。
